First aircraft seized in Malta
29th March 2012
Boeing 727, 727C, 727-100, 727- 100C, 727-200, and 727-200F series aircraft are subject to a new airworthiness directive issued by Boeing. This directive requires repetitive detailed inspections of the aft pressure bulkhead web for cracking, and repair if necessary. It also provides for an optional preventative modification of the aft pressure bulkhead web, which would terminate certain repetitive detailed inspections.
Boeing was prompted to issue the directive following reports of cracks in the aft pressure bulkhead web. The manufacturer wants ensure any cracks in the aft pressure bulkhead web are detected and corrected as they could adversely affect the structural integrity of the airplane, resulting in difficulty maintaining cabin pressurization or rapid decompression.
This directive is effective from February 14, 2011.
