Airworthiness Directive · Amendment 39-10735 · McDonnell Douglas Model MD-90-30 Series Airplanes
McDonnell Douglas Model MD-90-30 Series Airplanes
Model MD-90-30 series airplanes, as listed in McDonnell Douglas MD-90 Alert Service Bulletin MD90-27A032, dated June 22, 1998; certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model MD-90-30 series airplanes. This action requires a one-time inspection of the actuator attach bolts of the elevator load feel (ELF) located under the forward cockpit floor, and corrective actions, if necessary. This amendment is prompted by a report indicating that, during manufacture of an airplane, an actuator attach bolt of the ELF was installed improperly. The actions specified in this AD are intended to ensure that the actuator attach bolts are installed properly. Improper installation of such bolts could result in disconnection of the ELF mechanism, and consequent loss of pitch control of the airplane.
