Airworthiness Directive · Amendment 39-9860 · The Boeing Company Airplanes
The Boeing Company Airplanes
This AD applies to The Boeing Company 737-300 Series, 737-400 Series, 737-500 Series.
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), applicable to certain Boeing Model 737-300, -400, and -500 series airplanes, that requires inspections to detect bent or damaged tie links and washers of the elevator feel and centering unit, and replacement of the centering unit with a new or serviceable unit, if necessary. This amendment also provides an optional replacement of the centering unit, which, if accomplished with the installation of supports and a stop bolt, constitutes terminating action for the repetitive inspections. This amendment is prompted by a report of high control column forces that occurred during takeoff and landing. The actions specified by this AD are intended to prevent such high forces, which could result in restriction of elevator control during takeoff, climbout, and landing.
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.
