Airworthiness Directive · Amendment 39-10247 · Boeing Model 737-100, -200, -300, -400, and -500 Series Airplanes
Boeing Model 737-100, -200, -300, -400, and -500 Series Airplanes
Superseded. A later AD replaced this one: AD 98-03-09. Comply with the one in force.
All Model 737-100, -200, -300, -400, and -500 series airplanes, certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to all Boeing Model 737-100, -200, -300, -400, and -500 series airplanes. This amendment requires a one-time inspection to determine if certain ailerons are installed on the airplane. This amendment also requires removing any defective aileron, scrapping it, and replacing it with a new or serviceable aileron. This amendment is prompted by reports of failure of the aileron due to an inappropriate repair procedure. The actions specified in this AD are intended to detect and correct defective ailerons, which could result in in-flight separation of an aileron from the airplane and consequent reduced controllability of the airplane.
