Airworthiness Directive · Amendment 39-9303 · Learjet Inc. Airplanes
Learjet Inc. Airplanes
Superseded. A later AD replaced this one: AD 2003-19-11. Comply with the one in force.
This AD applies to Learjet Inc. 60.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Learjet Model 60 airplanes. This action requires inspection to detect bends in or damage to the fuel crossflow tube; inspection to determine clearance between the fuel crossflow tube and the flight control cables; and replacement or repair of the tube, if necessary. This amendment is prompted by reports of damage to the fuel crossflow tube and inadequate clearance between the fuel crossflow tube and the flight control cables due to bends in the fuel crossflow tube. The actions specified in this AD are intended to prevent chafing and eventual failure of the fuel crossflow tube due to inadequate clearance between the tube and the flight control cables; this condition could result in loss of fuel from one fuel tank during normal operating conditions or loss of fuel from both main fuel tanks during fuel cross feeding operations.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
