When are aircraft maintenance
records required?

Whenever any maintenance, preventive
maintenance, rebuilding, or alteration is
performed.
 Maintenance means inspection, overhaul,
repair, preservation, and the replacement of
parts (excludes preventive maintenance).
 In other words, you must make a record entry
for everything, including tire changes.
14 CFR 43.5 Approval for return to service
after maintenance, preventive maintenance,
rebuilding, or alteration.
• No person may approve for return to service any aircraft,
airframe, aircraft engine, propeller, or appliance, that has
undergone maintenance, preventive maintenance,
rebuilding, or alteration unless—
• (a) The maintenance record entry required by §43.9 or
§43.11, as appropriate, has been made;
• (b) The repair or alteration form authorized by or
furnished by the Administrator has been executed in a
manner prescribed by the Administrator; and
• (c) If a repair or an alteration results in any change in the
aircraft operating limitations or flight data contained in
the approved aircraft flight manual, those operating
limitations or flight data are appropriately revised and set
forth as prescribed in §91.9 of this chapter.

procedures used in doing it.
INCORPORATION BY REFERENCE

You don’t have to write a book.
The rule permits reference to technical
data in lieu of making a detailed entry.
Common references include maintenance
manuals, service letters, bulletins, work
orders, advisory circulars (AC43.13-1B),
and others.
Major alterations may reference STC’s.\
Reference documents must be retained.
IN ADDITION
 “major repairs and alterations shall be
entered on a form, and the form disposed
of, in a manner prescribed in appendix B,
by the person performing the work.”
 Requirements of appendix B have
changed!
 You will soon be able to file online.

Other Considerations
If you find the aircraft to be unairworthy,
you need to list the discrepancies. The
list must be signed and dated.
 For progressive inspections, the
certification statement is different.
 For other approved inspection programs,
the entry is made according to that
program.

FAR 91.417 (a)
“MAINTENANCE RECORDS”
• The owner/operator shall keep the
following records:
Records of the maintenance, preventive
maintenance, alterations, 100 hour,
annual, progressive and other required or
approved inspections, as appropriate.
 Total time in service for the aircraft, each
engine, each propeller, and each rotor.
 Current status of life-limited parts.
 Time since last required overhauls.

14 CFR 91.417 (b)(1)
The Owner or Operator shall retain all
maintenance records for 1 year after the
work is performed or until the work is
repeated or superseded by other work.
FAR 91.417 (b)(2)
 After one year, some maintenance records do
not have to be retained.
 For the most part, this pertains to repairs and
replacement of parts that are not life-limited.
 Altimeter/Transponder checks must be kept for
24 calendar months, or until repeated.
 All other records must be retained and
transferred with the aircraft at the time the
aircraft is sold.
Let’s talk about A.D.’s

The owner/operator shall keep records
containing “the current status of
applicable airworthiness directives
(AD) including, for each, the method
of compliance, the AD number, and
revision date. If the AD involves
recurring action, the time and date
when the next action is required.”
Breaking this down …….
 How do you determine the current status?
 What was the method of compliance?
 Do you enter the revision date?
 For recurring AD’s, do you enter the time and
date of next recurring action?
 Where do you make these entries?

Making it work for you.
• If it doesn’t say that you can’t, then you
can.
• Consider what the regulations don’t say.
• They don’t say that maintenance records
have to be kept in a bound logbook.
