§ 91.419

Transfer of maintenance

records.

Any owner or operator who sells a

U.S.-registered aircraft shall transfer
to the purchaser, at the time of sale,
the following records of that aircraft,
in plain language form or in coded form
at the election of the purchaser, if the
coded form provides for the preserva-
tion and retrieval of information in a
manner acceptable to the Adminis-
trator:

(a) The records specified in

§ 91.417(a)(2).

(b) The records specified in

§ 91.417(a)(1) which are not included in
the records covered by paragraph (a) of
this section, except that the purchaser
may permit the seller to keep physical
custody of such records. However, cus-
tody of records by the seller does not
relieve the purchaser of the responsi-
bility under § 91.417(c) to make the
records available for inspection by the
Administrator or any authorized rep-
resentative of the National Transpor-
tation Safety Board (NTSB).

§ 91.421

Rebuilt engine maintenance

records.

(a) The owner or operator may use a

new maintenance record, without pre-
vious operating history, for an aircraft
engine rebuilt by the manufacturer or
by an agency approved by the manufac-
turer.

(b) Each manufacturer or agency

that grants zero time to an engine re-
built by it shall enter in the new
record—

(1) A signed statement of the date the

engine was rebuilt;

(2) Each change made as required by

airworthiness directives; and

(3) Each change made in compliance

with manufacturer’s service bulletins,
if the entry is specifically requested in
that bulletin.

rebuilt engine is a used engine that has
been completely disassembled, in-
spected, repaired as necessary, reas-
sembled, tested, and approved in the
same manner and to the same toler-
ances and limits as a new engine with
either new or used parts. However, all
parts used in it must conform to the
production drawing tolerances and lim-
its for new parts or be of approved
oversized or undersized dimensions for
a new engine.
