The CAA review the escape systems fitted to other UK public transport aircraft certificated to an earlier standard and require similar action where doubts exist as to their effectiveness. 4.6. |
Issued: 01-DEC-2001 | To: CAA | 2001-13 |
The manufacturer and the CAA reassess the crashworthiness of the aircraft electrical system in the event of nose landing gear overload failure and take measures aimed at ensuring that safety-critical services remain operable in such a case. These services should include LP fuel cocks and engine bay fire extinguishers. |
Issued: 01-DEC-2001 | To: CAA | 2001-14 |
The CAA require the aircraft manufacturer to consider measures aimed at ensuring that the LP fuel heater assembly in the HS748 engine bay can tolerate the displacements likely to result from a major failure of the engine rotating assembly without releasing fuel. |
Issued: 01-DEC-2001 | To: CAA | 2001-15 |
The CAA review, in the light of advances in communication technology, its response to and reconsider Safety Recommendation 4.14, Aircraft Accident Report 8/88. |
Issued: 01-DEC-2001 | To: Rolls-Royce | 2001-16 |
The engine manufacturer undertake further research with the aim of determining the causes of in-service deviation from the installation setting of Dart engine fuel burner flow and developing means of preventing variation beyond acceptable limits. |
Issued: 01-DEC-2001 | To: Rolls-Royce | 2001-17 |
The engine manufacturer include a requirement in the Engine Overhaul Manual for an as-received burner flow check for the Dart engine at all maintenance shop visits. The Manual should also include requirements for any turbine disc action necessitated by the flow check results that fully reflect the latest knowledge on the possible effects of burner flow deviation on the discs. |
Issued: 01-DEC-2001 | To: CAA | 2001-18 |
The CAA review and revise as necessary the requirements for the recording of maintenance actions with the aim of ensuring that information essential to the further operation and maintenance of the aircraft is readily available. |
Issued: 01-DEC-2001 | To: CAA | 2001-19 |
The CAA require the engine manufacturer to designate repair schemes in such a way that the standard that has been used on any particular occasion is readily apparent. |
Issued: 01-DEC-2001 | To: CAA;Rolls-Royce | 2001-20 |
The engine manufacturer and the CAA reassess the susceptibility of the three-stage Dart turbine to HCF failure and ensure that effective action aimed at preventing recurrence has been taken. |
Issued: 01-DEC-2001 | To: CAA;Rolls-Royce | 2001-21 |
The CAA and the engine manufacturer consider the need for further improvement to their systems intended to ensure effective action to prevent recurrence following potentially catastrophic in-service failures of UK type-certificated equipment used on public transport aircraft. |
Issued: 01-DEC-2001 | To: CAA | 2001-22 |
The CAA review the adequacy of their current procedures to ensure that aircraft being entered into th~ UK Register have DFDR installations that satisfy the requirements of applicable performance specifications. |
Issued: 01-DEC-2001 | To: CAA | 2001-23 |
The CAA provide adequate guidance material on the subject DFDR installations to all personnel responsible for the surveying and regulation of such installations. |
Issued: 01-DEC-2001 | To: CAA | 2001-24 |
The CAA, in conjunction with operators, review the DFDR installation of aircraft on the UK Register which are fitted with the type PV1584 DFDR to determine compliance with the applicable minimum performance standards. |
Issued: 01-DEC-2001 | To: CAA | 2001-25 |
The CAA should require that, during a mandatory DFDR installation calibration, a range of expected data values should be stipulated for every point of a transducer\'s travel that is tested. These range values should be stated in either the calibration test procedure or the appropriate test results sheet. |
Issued: 01-DEC-2001 | To: CAA | 2001-26 |
The CAA should require that, during a mandatory readout of a DFDR, a section of the read out data should be examined to determine that all parameters have been recorded in accordance with the repetition rate specified in the data frame layout and conversion document pertinent to the DFDR installation being assessed. |
Issued: 01-DEC-2001 | To: CAA | 2001-8 |
The CAA require modification of the PA/Interphone system on HS 748 aircraft at the rear cabin attendant position to render the handset and its controls accessible to an attendant strapped into the aft cabin crew seat. |
