AD NUMBER: 2009-19-03

MANUFACTURER: British Aerospace Regional Aircraft Model HP.137 Jetstream Mk.1, Jetstream Series 200 and 3101, and Jetstream Model 3201 Airplanes
SUBJECT: Airworthiness Directive 2009-19-03

SUMMARY: BAE Systems have been notified by the main landing gear (MLG) radius rod manufacturer, APPH Ltd, that a batch of incorrectly manufactured Buffer Springs (part number 184818) has been supplied to their parts distributor and maintenance and repair organisation (MRO) facilities in North America.
There is a risk that any radius rod fitted with one of these incorrectly manufactured Buffer Springs could jam in an unlocked position. This condition, if not corrected, could result in MLG collapse and consequent injury to occupants of the aeroplane. EASA issued AD 2009-0121-E to require the replacement of the affected radius rods.
BAE Systems (Operations) Ltd Alert Service Bulletin (ASB) 32-A- JA090640 Revision 2 (the ASB) has now been issued, which identifies an additional seven affected radius rods by serial number (s/n).

This AD requires actions that are intended to address the unsafe condition described in the MCAI.
