EASA issued an emergency AD today notifying BAE Systems Jetstream operators that a problem with bad landing gear parts distributed in North America is a bit bigger than previously thought. From the directive:
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).
