100hr Check vs Annual Inspection, What’s the Difference?

What’s the difference between a 100-hr check and an Annual Inspection?

Annual Inspection or 100hr check - Sky Manor Air Repair

This is a question that frequently comes up. So much so, that we felt an in depth response was necessary to properly distinguish the two.

The reality is, they are virtually the same with only one major difference. Whether it is a 100-Hr Check or an Annual Inspection the scope of what is evaluated follows the same list from the aircraft manufacturer. The difference is in how they are handled.

A 100-Hr Check is only needed if the aircraft is being used for commercial purposes. They can be performed and signed off by any qualified technician, usually an Air-frame and Power Plant (A&P) mechanic.

However, if you put lots of flying time on your aircraft, say in the neighborhood of 200 hours or more annually, it would be highly recommended to have an inspection performed at the 100 hour interval even if the aircraft is not being flown for commercial purposes.

An Annual Inspection is a yearly evaluation required by most private and commercial aircraft. There are some exemptions to this as stated in CFR 14 FAR Part 91.409.

Most aircraft will simply require an annual inspection. While the inspected components are the same as that of a 100-Hr Check, ONLY an A&P Technician with Inspection Authority Certification, or IA, can sign off on the Annual Inspection Report.

As an example, the inspection report from Piper Aircraft clearly identifies that the type of inspection being performed must be circled in the top left corner of the form. The list of covered areas is the same.

If a 100-Hr check is required for your aircraft and one should fall during the time of an annual inspection, the annual inspection can take the place of the 100-Hr check. However, a 100-Hr check does NOT meet the requirements of the Annual Inspection.

Again, this is an administrative point as to who is authorized to sign off on the inspection.

For clarification, the 100-Hr Check and Annual Inspection programs can be replaced by other approved programs. However, these are usually reserved for larger, turbine powered aircraft which goes beyond the scope of this article.

Where do you turn to save money?

Saving money. Who doesn’t want to do that?

From printed catalogs that come stuffed in your mailbox to online parts websites, at Sky Manor Air Repair and Avionics we fully understand that there are many choices when it comes to saving money on aircraft parts.

Then, of course, there’s eBay, a very tempting option to source open box, over-stock, or pre-owned parts.

Do you use eBay? If not, you probably should. There are loads of good deals to be found there.

Wait, did I just tell people to go somewhere else to find cheap parts?

Hang on, before you get too click happy, you might want to read this story which highlights one customer’s experience using eBay to resource parts for his airplane – only a 3 minute read.

eBay - no way at Sky Manor Air Repair

Note, the story you are about to read is true. Only the names have been omitted to protect the innocent.*

Saving money is more than just the price of the part.

Recently, a plane was in our shop for a failed ‘component’ that by our recommendation needed to be removed, professionally overhauled, and reinstalled for a best case outcome – clearly a labor intensive job.

Upon hearing this advice and without professional consult the customer went online and found what he believed to be a viable pre-owned replacement part. After all, it appeared to match that of his own failed ‘component’.

He reasoned, this could easily save lots of labor time and costs.

Perhaps persuaded by a self-reliant attitude, well intentioned advice from friends, or even the overwhelming desire to save a few dollars, the decision was made to click the Order Now button.

All the customer needed to do now was wait for it to arrive, confident that a money saving solution was found.

Upon arrival it was brought to our shop with a request for us to install his newly acquired pre-owned part instead of the time consuming effort of overhauling the original. We graciously obliged his wishes.

After several attempts to make it work, there were just too many small differences between this used part and the one required to meet his application to ensure a proper fit.

It was disheartening for the customer to discover this misstep.

Yet, had he just discussed his thoughts and plans with us first before placing the order, we would have reinforced our original advice that the best savings based on our experience would be to overhaul his current part instead of buying a used one.

Had he still wanted to go with a used part we could have helped him with proper sizing so he wouldn’t have purchased one that did not fit – if only we had been included before clicking the magic button.

Rather than saving money, additional costs were accrued. There is the labor time our team needed to discover that it would not work, the freight costs of returning the wrong part (provided the eBay seller will even return it), and the time that was lost getting his aircraft ready for flight – a process that might have taken a month is now going on a month and a half and we are still not done.

Don’t underestimate the value that your maintenance team adds.

While some parts might look like an easy replacement from the online description or an ad in a catalog, all too often things are not as they may appear. Chances are quite high that your airplane maintenance staff has been down this road before. They have the experience to discern the various differences in aircraft models to know what will work and what will not.

Before you pull the trigger and order your aircraft parts from anyone other than your airplane maintenance team, do lots of homework to make sure it is the right part.

It’s also important to remember that most aircraft shops will not guarantee work they provide when installing parts that they themselves did not research and verify are correct for your make and model aircraft.

The knowledge and experience that your maintenance team provides can go a long way in helping you save money. In the long run they have your best interest at heart as they look to keep your business year after year.

Are you confident that the anonymous eBay seller feels the same?

Helping some lesser known hurricane victims

FlyPups.org at Sky Manor Air Repair

Sky Manor Air Repair and Avionics recently had the remarkable pleasure of indirectly helping a great group of people complete their mission to rescue 31 dogs from harm’s way.

Last month Hurricane Harvey forced millions of families to leave their homes. Many faced the difficult decision to put their pets in a shelter or simply leave them behind. Rising flood waters forced many of these abandoned dogs further into outlying areas and overcrowded kennels. With limited resources and the growing need for space, some dogs will ultimately be euthanized.

That’s where FlyPups came in, but they needed some help.

FlyPups.org at Sky Manor Air RepairSky Manor Air FlyPups.org at Sky Manor Air RepairRepair and Avionics got the call just before Labor Day that a plane needed priority status on an annual inspection for a critical mission ahead – flying supplies to Mississippi and returning to the Northeast with, hopefully, 31 rescued dogs.

The team jumped to the task of expediting a thorough inspection of Matthew Kiener’s Piper Saratoga in order to get it mission ready. Matthew is the Founder, Chairman, and Chief Volunteer Pilot of FlyPups.org – an organization committed to moving dogs at risk of being euthanized to non-kill shelters and fosters allowing adoptions to be facilitated and placing them in loving homes.

According to Matthew, “Jay, Jamie, Dana and the rest of the team at Sky Manor Air Repair really came through [for us]. I’m certain that Jay and Jamie did a most excellent and thorough inspection. The plan is to fly supplies to Mississippi tomorrow [Sunday 9/3/2017] and return Monday with 31 dogs. We are trying to clear out shelters in the areas surrounding Texas so the dogs in the flood zones can occupy these shelters. It’s important that we don’t pull people’s pets and bring them this far north without giving them the opportunity to be reunited.”

“And while she didn’t turn any wrenches, Dana was not only instrumental in the facilitation of the expedited annual inspection, she along with Jay & Jamie, have been very kind and supportive of the FlyPups effort.”

All of us at Sky Manor Air Repair and Avionics were proud to be part of this worthy effort.

Engine Pre-Flight Inspection Tip – For the Non-Mechanic

Pre-flight inspections – among the many other flight-critical aircraft components that are part of your routine, you’ve likely checked the airframe, tested the fuel, and reviewed the brakes and tires. Customarily you have also opened the cowl and looked over the engine, searching for anything that might stand out as an ‘area of concern’.

But are you really clear on what to look for under the cowl?

As a pilot, there are no expectations for you to be a mechanic, verse in every aspect of engine function and maintenance. During pre-flight inspection, however, pilots do have the responsibility to look under the cowl and have the where-with-all to identify areas of potential concern. For those that are less mechanical, looking at an engine can seem a bit intimidating.

Fortunately, you don’t need to be a mechanic to catch a small issue. All you need to be is attentive to changes that vary from the normal in order to identify a potential problem before it becomes a larger issue.

Some things to consider:
• Color changes on components
• Cracked hoses
• Oil drips

In the following example, exhaust soot was discovered on one of the ignition wires during annual inspection. Clearly this is not a place to find evidence of exhaust. Yet this very visible change was not caught during the last pre-flight inspection. A thorough examination with the aid of a flashlight revealed a crack near the top of the exhaust pipe – the cause of the errant soot.

Cracked Exhaust Pipe Continental Engine

In this case, the issue was caught without incident. Gone unnoticed or left unattended this could have developed into a greater concern.

Take the time to know and understand how things should look. Does anything appear out of the ordinary? Pay attention to consistencies. If something looks different, note the change, and above all ask questions. Bring it to the attention of your maintenance team to determine cause and solution.

If you have questions regarding what to look for while performing a pre-flight on the engine, please contact Sky Manor Air Repair and Avionics for details.

Growing to Serve You Better

It’s been five years already? It seems like just yesterday that we opened our doors here at Sky Manor Airport with just two IA’s under one roof. Our goal then, as it remains today, was a simple one; provide quality aircraft maintenance that is On Time and On Budget with a commitment to treating customers as we ourselves would expect to be treated.

Since then we have expanded our operation to include an avionics CRS, two spacious hangars, and a team of technicians qualified to handle all aspects of GA maintenance, inspections, and installations.

The huge demand to equip aircraft with the latest ADS-B components, coupled with our new Garmin Dealership status, has meant that even more hands are needed on deck to handle the load and continue the level of service that you have come to expect from us.

Therefore, we are very proud and excited to announce that we have added two new and highly qualified members to our ranks here at Sky Manor Air Repair and Avionics. Please join us in welcoming Chris Baum and Steve Bueno!

Chris Baum, Avionics Technician

What’s your perception of the ADS-B mandate?

Perception is everything, right?

When it comes to the ADS-B Mandate, there’s plenty to go around as many people have their own interpretation on how they will handle the reality of meeting the January 2020 deadline.

Perception #1 – Prices will keep going down. Therefore, why make an investment too soon. As a general rule technology eventually comes down in price the longer it is in the market. But today’s marketplace is full of new vendors that have driven the cost down. No longer are the biggest names in navigational equipment the only players that can dictate the price. Competition for the ADS-B pie has ruled the day, so don’t expect bigger price drops any time soon. In fact, they may even go up as supply and demand shifts the closer we get to 01/01/20.

Plus – right now the Government is giving away $500 for up to 20,000 installs which are going fast. So why not get a little bit back from ‘The Man’? That’s $500 less than you will be spending later!

Perception #2 – I have a good relationship with my Avionics guy, he’ll fit me in anytime. Why do now when I have 3 more years? While having a good relationship with your CRS is always appreciated, the reality is that shops are getting booked up. There are only so many hours available and too many planes to fit in. While it might be the best intention for your shop to ‘fit you in’, the only times that might be available to you could be premium Saturday or even Sunday rates. But even those might be booked as we get closer to the mandate.

The point here is not to procrastinate. Think ahead or you could wind up paying more than those acting today or, at worst, find yourself grounded without a certified aircraft after Jan 1, 2020.

This is a complicated situation – we get it. Many people have questions. If you do, you are not alone. Contact us today for more details.

A simple way to save money on your next annual or 2 year certification.

Time is Money.
What you remember to bring to your next service could save you both.

Maybe your running late on your 2-year Transponder and Altimeter Cert. Or perhaps the avionics office called to tell you your new glass panel is in and ready for installation. Either way, the excitement of getting your plane in quickly may have left you forgetting something important at home on your desk.

When bringing in your plane for service, making sure you have everything in hand, or in the plane, can not only help us to serve you better, but might even save you a few dollars as well. Here’s how…

Items to

For Transponder/Altimeter Checks
Air-frame Logbooks

  • Retrieving component serial numbers from the log book rather than having to locate them within the aircraft can save an enormous amount of billable time.
  • Many components are difficult to access and require disassembly and reassembly of many features in order to locate the components and record this important information.
  • Plus, we rather save you the money and us the time!

For Avionics Installations
Air-frame Logbooks
Weight & Balance Report (Plus History Too)
Flight Manual Supplements

  • Having copies of old Weight & Balance Reports can offer our technicians a history of previous mounting locations of your current equipment.
  • Not only will this save you billable time from having to locate otherwise hidden components, it can offer our technicians insight into how best to mount your newer equipment.

We mention the need for these items in order to perform our best service to you, yet so often one or more of these documents are missing from the aircraft.

Additionally, in order to be flight legal, it is required that the Flight Manual Supplements and copy of the most recent Weight & Balance report be in the aircraft. Please don’t leave them home.

If you have questions regarding your next service visit, please reach out to us in advance. We would be happy to go over everything that’s needed to perform our best work for you – and in the least amount of time as well.
