Plain English Summary

2/10 complexity

Mechanically, this Airworthiness Directive requires operators of British Aerospace Jetstream 3100/3200 aircraft fitted with specified main landing-gear radius rods (left P/Ns 1847/A–/L; right P/Ns 1862/A–/L) to carry out the actions in BAE Systems Alert Service Bulletin ASB 32-A-JA010740 Revision 2 by 22 September 2001 (effective 22 August 2001). The measure responds to a manufacturing heat‑treatment error that can weaken radius rods and risk landing-gear collapse during abnormal events, so affected rods must be inspected/marked or removed per the service bulletin.

AD/JETSTREAM/91 Main Landing Gear Radius

AD/JETSTREAM/91 Main Landing Gear Radius Rods 10/2001

Applicability: All Jetstream 3100 and 3200 Series aircraft with radius rods part numbers 1847/A through /L (left) and 1862/A through /L (right) installed.

Requirement: Action in accordance with BAE Systems Alert Service Bulletin ASB 32-A-JA010740 Revision 2.

Note: For aircraft on which the Requirement document at original issue has already been accomplished, Revision 2 may require further work to mark affected radius rods with a date for their removal from service.

Compliance: Before 22 September 2001, unless already accomplished.

This Airworthiness Directive becomes effective on 22 August 2001.

Background: Due to an error in the manufacturing process the material of some radius rod cylinders, part number 184811, may not have received the correct heat treatment. This condition can result in failure of the radius rod and collapse of the landing gear during an abnormal event, such as a heavy landing.
