Boeing 767 Series Aeroplanes AD/B767/218 Off-Wing Escape System 3/2006

Applicability: Model 767-200 and -300 series aircraft; equipped with off-wing emergency escape slides, as identified in Boeing Special Attention Service Bulletins 767-25-0358 and 767-25-0317. Requirement: Action in accordance with the technical requirements of FAA AD 2005-25-23 Amdt 39-14416. Compliance: As specified in the Requirement document, with a revised effective date of 16 March 2006. This Airworthiness Directive becomes effective on 16 March 2006. Background: The FAA received a report indicating that the inflation trigger cable may inadvertently disconnect from the inflation turnbuckle of the inflation cylinder of the off-wing emergency escape slide, due to incorrect spacing of the cable insertion gap; and additional reports indicating that the pull force increase mechanism on the off-wing charged cylinder assemblies of the escape slide may be inadvertently disengaged. Failed deployment of the emergency escape slide during an emergency could impede an evacuation and result in injury to passengers and crew, or inadvertent inflation and loss of the escape slide during flight could result in structural damage to the aircraft.
