Aircraft Maintenance Requirements Flashcards
Who is responsible for ensuring that an aircraft is maintained in an airworthy condition?
The owner or operator
After aircraft inspections have been made and defects have been repaired, who is responsible for determining that the aircraft is in an airworthy condition?
The pilot in command is responsible for determining whether the aircraft is safe for flight
Can you legally fly an aircraft that has an inoperative flap position indicator?
If the aircraft is operated under part 91 without an approved MEL then no, inoperative equipment must be repaired or removed from the aircraft. If the MEL states that the aircraft can be operated without the equipment then the aircraft must be operated under all applicable conditions and limitations.
Can an aircraft operator allow flight operations to be conducted in an aircraft with known inoperative equipment without an approved MEL?
Only if the equipment meets the following criteria:
a. inoperative instruments or equipment cannot be required
1. for day VFR
2. on the aircraft’s equipment list
3. for the specific kind of operation by the regulations
4. by an airworthiness directive
and
b. the inoperative equipment must be
1. removed from the aircraft and logged in the maintenance record
or
2. deactivated and placarded “inoperative” and logged in the maintenance record.
or
c. under a special flight permit
Who is authorized to determine if a placarded inoperative instrument constitutes a hazard to the aircraft?
a. a pilot who is appropriately rated
b. or by a mechanic who is appropriately rated on the aircraft.
What are Minimum Equipment Lists? (MELs)
a precise list of instruments, equipment and procedures that allow the aircraft to be flown under specific conditions with inoperative equipment.
What is an aircraft equipment list, and where is it found?
a. specifies all the required equipment, and all equipment approved for installation in the aircraft. The weight and arm of each item is included on the list.
b. the list is usually found with the weight and balance data.
What must happen if an AMT removes or installs a piece of equipment that is on the aircraft equipment list?
the weight and balance data must be updated
How long can an aircraft be flown with inoperative equipment on board?
when the aircraft is due for inspection all inoperative items should be repaired or replaced.
What regulations apply concerning the operation of an aircraft that has had alterations or repair which may have substantially affected its operation in flight?
an appropriately-rated pilot with at least a private pilot certificate must:
a. fly the aircraft
b. make an operational check of the maintenance performed
c. log the flight in the aircraft log
How long does the Airworthiness Certificate of an aircraft remain valid?
they are effective indefinitely as long as
a. all required maintenance and alterations are performed
b. and the aircraft is registered in the United States
What are the required maintenance inspections for aircraft?
a. annual inspections - every 12 calendar months
b. 100-hour inspection - if carrying passengers for hire or giving flight instruction
Can a 100 hour inspection be substituted for an annual inspection?
No. The annual inspection is acceptable as a 100 hour inspection, but the reverse is not true. The 100 hour can be signed off by an A&P mechanic but the annual must be signed off by an Inspection Authorization (IA) Certificate holder
What are the required tests and inspections of aircraft and equipment to be legal for both VFR and IFR flight?
a. Annual inspection
b. 100-hour inspection (if carrying any person for hire)
c. Static system check (every 24 months)
d. Transponder check (every 24 months)
e. Altimeter check (every 24 months)
f. VOR checked (every 30 days)
g. ELT inspection (every 12 months)
What aircraft preventive maintenance can a certified pilot perform?
If the aircraft is not used in air carrier service, a certified pilot may perform basic preventive maintenance such as, oil changes, wheel bearing lubrication and hydraulic fluid refills.
