Aircraft documents
There are numerous documents that should be
reviewed and transferred when you purchase an
aircraft.
Bill of Sale or Conditional Sales Contract
The bill of sale or conditional sales contract is your
proof of purchase of the aircraft and will be recorded
with the FAA to protect your ownership interest.
Airworthiness Certificate
The aircraft should have either FAA Form 8100-2,
Standard Airworthiness Certificate, or FAA Form
8130-7, Special Airworthiness Certificate.
Maintenance Records
The previous owner of the aircraft should provide
the aircraft’s maintenance records containing the
following information:
• The total time in service of the airframe, each
engine, and each propeller;
• The current status of life-limited parts of each
airframe, engine, propeller, rotor, and appliance;
• The time since last overhaul of all items installed
on the aircraft that are required to be overhauled
on a specified time basis;
• The identification of the current inspection status
of the aircraft, including the time since the last
inspection required by the inspection program
under which the aircraft and its appliances are
maintained;
• The current status of applicable ADs, including
for each the method of compliance, the AD
number, revision date, and if the AD involves
recurring action, the time and date when the next
action is required; and

manuals
Manufacturers produce owner’s manuals, main-
tenance manuals, service letters and bulletins, and
other technical data pertaining to their aircraft.
These may be available from the previous owner, but
are not required to be transferred to a purchaser.
If the service manuals are not available from the previous owner, you can usually obtain them from
the aircraft manufacturer.
Airworthiness
Two conditions must be met for a standard category
aircraft to be considered airworthy:
• The aircraft conforms to its type design (type
certificate). Conformity to type design is attained
when the required and proper components are
installed that are consistent with the drawings,
specifications, and other data that are part of the
type certificate. Conformity includes applicable
Supplemental Type Certificate(s) (STC) and
field-approval alterations.
• The aircraft is in condition for safe operation,
referring to the condition of the aircraft with
relation to wear and deterioration.
maintenance
14 CFR part 91, section 91.403, places primary
responsibility upon the owner for maintaining the
aircraft in an airworthy condition. This includes
compliance with applicable ADs. The owner is
responsible for ensuring that maintenance personnel
make appropriate entries in the aircraft main-
tenance records, indicating that the aircraft has been
approved for return to service. In addition, the owner
is responsible for having maintenance performed
that may be required between scheduled inspections.
Inoperative instruments or equipment that can be
deferred under 14 CFR part 91, section 91.213(d)(2),
will be placarded and maintenance recorded in
accordance with 14 CFR part 43, section 43.9.
Pre-Purchase inspection
Before buying an aircraft, you should have a mechanic
you trust give the aircraft a thorough inspection
and provide you with a written report of its condition.
While a pre-purchase inspection need not be an
annual inspection, it should include at least a dif-
ferential compression check on each cylinder of the
engine and any other inspections necessary to
determine the condition of the aircraft. In addition
to a mechanical inspection, the aircraft logbooks
and other records should be carefully reviewed for
such things as FAA Form 337, Report of Major
Repair or Alteration, AD compliance, the status of
service bulletins and letters, and aircraft/component
serial numbers.

aviation community, specific to the United States.
