Some fatal GA accidents have been caused by flying an aircraft that was undergoing maintenance and not approved for return to service.
This led to a new FAA Safety Briefing that delves into what you need to know before flying an aircraft that has been undergoing maintenance.
“Before you take or fly an aircraft, always check for the signed Approval for Return to Service entry in the aircraft’s logbook,” the safety briefing begins.
“Most aircraft owners are up to speed on the status of their aircraft, and rental fleets usually have aircraft status boards or squawk sheets to check for problems with an airplane, but nevertheless some pilots take, or attempt to fly, an airplane that is undergoing maintenance or is not ready to be returned to service,” the briefing continues.
Always Check the Logbook
Never assume that an aircraft is ready to fly.
For example, if your mechanic tells you that the repairs are done and that all the work is documented on the work order, does that mean your aircraft is ready to fly? How about when that big, red “Do Not Fly” sign is no longer hanging on the yoke — does that mean your aircraft is approved for flight? In each of these cases, the answer is — absolutely not.
You have to check the aircraft’s logbook first, FAA officials advise. Do not take an airplane until you have seen the signed Approval for Return to Service entry in the aircraft’s logbook.
An Approval for Return to Service is a documentation in your aircraft’s logbook with the signature and certificate number of the person approving your aircraft for return to service. It is a written certification that tells you whether the aircraft is airworthy and ready to fly.
Per 14 CFR section 43.9, any person who performs maintenance, repairs, or alterations on an aircraft must make an entry in the maintenance record with the following information:
- A description of the work performed,
- The date the work was completed,
- The name of the person who performed the work, and
- The signature and certificate number of the person approving the work.
The signature and certificate number make up the Approval for Return to Service.
Keep in mind that the Approval for Return to Service is only for the work performed. Make sure that all the required inspections have been completed and logged, FAA officials note.
After an inspection, your maintenance record entry should contain:
- A certification statement such as: ‘‘I certify that this aircraft has been inspected in accordance with XYZ inspection and was determined to be in airworthy condition.’’
- The date of the inspection,
- The aircraft total time in service, and
- The signature, certificate number, and kind of certificate held by the person approving return to service.
You should see this for every inspection.
Inspect the Aircraft
It’s always a good idea to do an advanced preflight on an aircraft that has been returned to service.
Your advanced preflight should start with the aircraft documentation. Make sure the maintenance work has been documented in the appropriate aircraft log book, and check that the aircraft has been returned to service.
If the aircraft was test flown, there may be a discrepancy between the
logbook time and what you see on the panel. Take your time looking the aircraft over.
Other tips from the FAA safety team:
- Use a checklist to make sure you don’t miss anything.
- Pay particular attention to the areas that were worked on, including any disconnections that may have been required to access the parts that were serviced.
- Special attention should be paid to things like oil leaks and loose fasteners.
- For the first flight, stay in the pattern within gliding distance of your runway.
It is Your Responsibility
As the aircraft owner, it is your responsibility to ensure that maintenance personnel make the appropriate entries in the aircraft logbook.
Proper logbook entries that detail the work completed not only keep you up to speed on the condition of your aircraft, but they also serve as an important factor in maintaining the airworthiness and long term value of your airplane.
As a best practice, always check the logbooks after an aircraft is returned from maintenance.
And before you take or fly that aircraft, always look for the signed Approval for Return to Service entry. That way you’ll know that your aircraft is ready to fly.
About 25 years ago I picked up my Piper Lance from the shop after an annual. While preparing for my first flight and doing the pre-take off checks, I noticed that the controls were not “free and correct”. I was unable to move the yoke full forward. After a few minutes of wrangling with the yoke, I felt a hard thump on my shin. I looked down to see my mechanic’s Makita cordless drill lying on the floor. Apparently he had been working up behind the panel and had left the drill suspended up on the control mechanism. Now, a T-Tail Lance isn’t the most pitch stable aircraft ever built but I can only imagine how things could have gone had I not done a careful pre flight check.
Trusting an entry in a logbook is your golden rule? After an annual I plan on a conversation with the mechanic(s) and a complete preflight with checklists in hand. Then starting the plane and an extra long taxii and runup with someone else in the cockpit checking things. Then a couple of patterns with touchNgoes before departing to anywhere away from the airport.
ohhh very true, an acquaintance years back went after hours to pick up his Aztec from the shop, where the owner was also a personal friend, upon starting the left engine, a horrible shaking and noise erupted, the left propeller had been off, and replaced, but not torqued down, and no notification was anywhere to be found, AND the logbook was signed off as airworthy..”He learned about flying from that”, so did I
