Unfallbericht:
The Premier 1 departed on a flight from Humberside to Dublin with the pilot and six passengers on board. Once airborne the pilot attempted to raise the landing gear, but although the control handle moved the landing gear remained in the fully extended position with three green lights illuminated on the landing gear indicator. The pilot attempted to re-cycle the landing gear but without success; later he noticed that he also had indications of LIFT DUMP FAIL and ANTI SKID FAIL. He diverted to Farnborough. After touchdown the pilot attempted to deploy the lift dump system but, as expected, the lift dump spoilers failed to extend. After discussing the problem with the aircraft's maintenance organisation, the aircraft was flown to Blackbushe for further technical investigation. After landing on runway 26 (4400 feet long) the aircraft left the runway, struck a series of obstructions and was destroyed.
The support bracket for the right main landing gear weight-on-wheels switch was found to have sustained a pre-impact failure which accounted for the indications reported by the pilot.

Sicherheitsempfehlungen

AAIB issued 5 Safety Recommendations

Issued: --	To: Raytheon	2004-95
It is recommended that Raytheon Aircraft Company review the design and installation of the weight-on-wheels switches and support hardware fitted to the Premier 1 aircraft, with a view toreducing the possibility of stress corrosion cracking. (Accepted - closed)
Issued: --	To: Raytheon	2004-96
It is recommended that Raytheon Aircraft Company review the logic of displaying a LIFT DUMP FAIL and inhibiting the system due to a weight-on-wheels switch disagree on the Premier 1 aircraft, and modify the system so that lift dump remains available. (Accepted - closed)
Issued: --	To: Raytheon	2004-97
It is recommended that Raytheon Aircraft Company review the logic of displaying ANTI SKID FAIL for a weight-on-wheels switch disagree on the Premier 1 aircraft, when the system is otherwise operational. (Accepted - closed)
Issued: --	To: Raytheon	2004-98
It is recommended that Raytheon Aircraft Company should carry out the following amendments to the Airplane Flight Manual for the Premier 1 aircraft: 1. Revise the Lift Dump Failure (Lift Dump Annunciator Illuminated) abnormal checklist to include recommendations on required braking technique and to include the warning of braking efficiency published as part of the Lift Dump Fails to Extend (Lift Dump Warning Tone Sounds) emergency checklist. 2. Review all Airplane Flight Manual and abbreviated checklists to ensure that flight critical items included in Warnings and Cautions in the Airplane Flight Manual are included in the appropriate abbreviated checklists. 3. Expand the Performance section of the Airplane Flight Manual to include advice and, where appropriate, data for multiple system failures. 4. Amend, where appropriate, performance charts to include all associated conditions on which the published performance is based. (Accepted - closed)
Issued: --	To: Raytheon	2004-99
It is recommended that Raytheon Aircraft Company review the presentation of performance data in the Airplane Flight Manual for the Premier 1 aircraft to render it less susceptible to errors in interpretation. (Accepted - closed)
