§ 91.1505

Repairs assessment for pres-

surized fuselages. 

(a) No person may operate an Airbus 

Model A300 (excluding the -600 series),

McDonnell Douglas Model DC–8, DC–9/ 
MD–80 or DC–10, Fokker Model F28, or 
Lockheed Model L–1011 airplane beyond 
applicable flight cycle implementation 
time specified below, or May 25, 2001, 
whichever occurs later, unless repair 
assessment guidelines applicable to the 
fuselage pressure boundary (fuselage 
skin, door skin, and bulkhead webs) are 
incorporated within its inspection pro-
gram. The repair assessment guidelines 
must be approved by the responsible 
Aircraft Certification Service office for 
the type certificate for the affected air-
plane.

B4–2C): 30,000 flights above the window 
line, and 36,000 flights below the win-
dow line. 

(iii) Model B4–200: 25,500 flights above 

the window line, and 34,000 flights 
below the window line. 

(2) For all models of the British Aero-

space BAC 1–11, the flight cycle imple-
mentation time is 60,000 flights. 

(3) For all models of the Boeing 707, 

the flight cycle implementation time is 
15,000 flights. 

(4) For all models of the Boeing 720, 

the flight cycle implementation time is 
23,000 flights. 

(5) For all models of the Boeing 727, 

the flight cycle implementation time is 
45,000 flights. 

(6) For all models of the Boeing 737, 

the flight cycle implementation time is 
60,000 flights. 

(7) For all models of the Boeing 747, 

the flight cycle implementation time is 
15,000 flights. 

(8) For all models of the McDonnell 

Douglas DC–8, the flight cycle imple-
mentation time is 30,000 flights. 

(9) For all models of the McDonnell 

Douglas DC–9/MD–80, the flight cycle 
implementation time is 60,000 flights. 

(10) For all models of the McDonnell 

Douglas DC–10, the flight cycle imple-
mentation time is 30,000 flights. 

(11) For all models of the Lockheed 

L–1011, the flight cycle implementation 
time is 27,000 flights. 

(12) For the Fokker F–28 Mark 1000, 

2000, 3000, and 4000, the flight cycle im-
plementation time is 60,000 flights.
