Aviation safety issues and actions
Recommendation issued to: US Federal Aviation Administration
|Date issued:||25 October 2004|
|Safety action status:|
On 7 September 2004, at about 0710 Eastern Standard Time, while
passing FL175, during a gradual descent from flight level (FL) 220,
the pilot of the Raytheon B300 aircraft, registered VH-KJD, heard a
loud muffled thud and then air noise. The pilot saw that the cabin
door had separated from the aircraft fuselage.
The Australian Transport Safety Bureau recommends that the US
Federal Aviation Administration advise operators of Beechcraft King
Air and Raytheon King Air aircraft of the potential safety
deficiency of the cabin door warning system becoming prematurely
earthed, resulting in a sense switch or switches no longer
providing an electrical signal for its or their position.
The recommendation was simultaneously issued as R20040074 to the Civil Aviation Safety Authority.
|Date issued:||05 July 2006|
|Response from:||US Federal Aviation Administration|
|Action status:||Closed - Accepted|
No response received.
No response was received on this recommendation. However, the aircraft manufacturer issued mandatory service bulletin SB 52-3701 which addressed this anomaly. The Australian Transport Safety Bureau considers this action sufficient to close this recommendation.
