Airworthiness Directive · Amendment 39-13262 · Learjet Model 45 Airplanes
Learjet Model 45 Airplanes
Model 45 airplanes, serial numbers 45-005 through 45-208 inclusive, 45-210 through 45-222 inclusive, 45-224, 45-225, 45-227, and 45-229 through 45-231 inclusive; certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Learjet Model 45 airplanes. This action incorporates a reduced life-limit replacement interval for certain shear pins in the trunnion assemblies of the main landing gears (MLG) into the airworthiness limitations section of the Instructions for Continued Airworthiness, and requires replacement of those certain shear pins with new, improved shear pins. This action is necessary to prevent failure of the shear pins in the trunnion assemblies of the MLGs, which could result in the collapse of a MLG, and consequent reduced controllability of the airplane during takeoff or landing. This action is intended to address the identified unsafe condition.
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.
