Importance of Placards and Lockout/Tagout ProceduresGrab the keys and go! In aviation, we know thats not quite the case when piloting an aircraft. In addition to your other pre-check procedures, have you considered the aircrafts current maintenance status?
The General Aviation Joint Steering Committee (GAJSC) has identified a number of fatal general aviation accidents caused by flying in an aircraft that is undergoing maintenance and has not yet returned to service. Yikes! How do you know your aircraft is safe? We suggest you consider adopting an informal lockout/tagout procedure to ensure that you, and other pilots, are aware that the aircraft youre about to fly may not have been returned to service.
Why Placard?Placards are common in many general aviation aircraft, and for good reason: the message they display is mandatory. In fact, Title 14 of the Code of Federal Regulations (14 CFR) section 91.9 (a) says, in part, that no person may operate a civil aircraft without complying with the operation limitations specified inthe approved Airplane or Rotorcraft Flight Manual, markings, and placards.
Placards also alert us to non-working equipment or instruments. You may operate most types of light aircraft with inoperative instruments, as long as they are not part of the VFR day type certification. In addition, the aircraft must have a placard that says inoperative. If the instrument is removed from the aircraft, a placard must provide the status. In all cases, the pilot or mechanic must determine that the inoperative instrument does not pose a hazard to flight safety. There are a lot more requirements to this part, so please read 14 CFR section 91.213 in its entirety, if this situation applies to you.
Shared ResponsibilityPilots and mechanics share a responsibility to indicate properly inoperative instruments or equipment. Look at 14 CFR section 91.405; it requires owners or operators to have inoperative instruments or equipment repaired, replaced, removed, or inspected at the next required inspection with placards installed, as required.… Read more ...
