§ 135.419

Approved aircraft inspection 

program. 

(a) Whenever the Administrator finds 

that the aircraft inspections required 
or allowed under part 91 of this chapter 
are not adequate to meet this part, or 
upon application by a certificate hold-
er, the Administrator may amend the 
certificate holder’s operations speci-
fications under § 119.51, to require or 
allow an approved aircraft inspection 
program for any make and model air-
craft of which the certificate holder 
has the exclusive use of at least one 
aircraft (as defined in § 135.25(b)). 

(b) A certificate holder who applies 

for an amendment of its operations 
specifications to allow an approved air-
craft inspection program must submit 
that program with its application for 
approval by the Administrator. 

(c) Each certificate holder who is re-

quired by its operations specifications 
to have an approved aircraft inspection 
program shall submit a program for ap-
proval by the Administrator within 30 
days of the amendment of its oper-
ations specifications or within any 
other period that the Administrator 
may prescribe in the operations speci-
fications. 

(d) The aircraft inspection program 

submitted for approval by the Adminis-
trator must contain the following: 

(1) Instructions and procedures for 

the conduct of aircraft inspections 
(which must include necessary tests 
and checks), setting forth in detail the 
parts and areas of the airframe, en-
gines, propellers, rotors, and appli-
ances, including emergency equipment, 
that must be inspected. 

(2) A schedule for the performance of 

the aircraft inspections under para-
graph (d)(1) of this section expressed in 
terms of the time in service, calendar 
time, number of system operations, or 
any combination of these. 

(3) Instructions and procedures for 

recording discrepancies found during 
inspections and correction or deferral 
of discrepancies including form and 
disposition of records. 

(e) After approval, the certificate 

holder shall include the approved air-
craft inspection program in the manual 
required by § 135.21. 

(f) Whenever the Administrator finds 

that revisions to an approved aircraft 
inspection program are necessary for 
the continued adequacy of the pro-
gram, the certificate holder shall, after 
notification by the Administrator, 
make any changes in the program 
found by the Administrator to be nec-
essary. The certificate holder may pe-
tition the Administrator to reconsider 
the notice to make any changes in a 
program. The petition must be filed 
with the representatives of the Admin-
istrator assigned to it within 30 days 
after the certificate holder receives the 
notice. Except in the case of an emer-
gency requiring immediate action in 
the interest of safety, the filing of the 
petition stays the notice pending a de-
cision by the Administrator. 

(g) Each certificate holder who has 

an approved aircraft inspection pro-
gram shall have each aircraft that is 
subject to the program inspected in ac-
cordance with the program. 

(h) The registration number of each 

aircraft that is subject to an approved 
aircraft inspection program must be in-
cluded in the operations specifications 
of the certificate holder.
