Issued: 25-AUG-1985 | To: JT8D-15 | T85-17-51 |
Immediate inspection for evidence of combustion chamber distress (and repair or replacement, if necessary) of all JT8D-15 engines with certain combustion chambers (Part Nos. 778714 and 778715), except for those engines maintained under an ECM program approved by the FAA. |
Issued: 19-SEP-1985 | To: CAA | G-BGJL (10) |
A review of the approval of the cabin configuration as it existed on G-BGJL should be conducted, with particular reference to the following features of that configuration: i) The restricted view of the passenger cabin afforded the forward cabin crew when seated.; ii) The forward aisle restriction created by the floor to ceiling forward galleys.; iii) Access to the overwing exit where the presence of row 10 seats appeared to conflict with the British Civil Airworthiness Requirements. It is recommended that all row 10 seats be removed. The approval of other configurations on Boeing 737 and other types should also be reviewed with the intention of addressing any similar problems. |
Issued: 19-SEP-1985 | To: CAA | G-BGJL (5) |

Issued: 04-DEC-1985 | To: CAA | G-BGJL (24) |
The Civil Aviation Authority should urgently give consideration to the formulation of a requirement for the provision of smokehoods/masks to afford passengers an effective level of protection during fires which produce a toxic environment within the aircraft cabin. |
Issued: 14-MAR-1986 | To: CAA | G-BGJL (1) |
Procedures should be developed to enable the crew to position an aircraft, when a ground fire emergency exists, with the fire downwind of the fuselage. Visual indicators of local wind direction located within the manoeuvre areas would be valuable aids to the implementation of such a procedure. |
Issued: 15-DEC-1988 | To: | G-BGJL (11) |

Issued: 15-DEC-1988 | To: | G-BGJL (16) |
RFF personnel in breathing apparatus should be positioned by overwing and other exits at the earliest opportunity to assist those evacuating and to help keep the exits clear. This would require the airport fire service to be equipped with additional breathing apparatus and all RFF personnel to be trained in its use. |
Issued: 15-DEC-1988 | To: | G-BGJL (17) |
A requirement should be introduced for some form of standardised high visibility clothing to be worn by the officer in charge of the Rescue and Fire Fighting personnel at any incident/accident scene. |
Issued: 15-DEC-1988 | To: | G-BGJL (18) |

Issued: 15-DEC-1988 | To: | G-BGJL (2) |
Research should be undertaken into methods of providing the flight deck crew with an external view of the aircraft, enabling them to assess the nature and extent of external damage and fires. |
Issued: 15-DEC-1988 | To: | G-BGJL (20) |
The balance of effort in aircraft fire research should be restored by increased effort directed towards fire hardening of the hull, the limitation of fire transmission through the structure and the prevention of structural collapse in critical areas. Short term measures should be devised for application to existing types but, in the long term, fire criteria should form a part of international airworthiness requirements. |
Issued: 15-DEC-1988 | To: | G-BGJL (21) |
A requirement should be introduced to ensure that existing external fuel tank access panels which are vulnerable to impact from engine or wheel/tyre failures on aircraft in service are at least as impact resistant as the surrounding structure. The potential risk of damage from debris impacts should be addressed in future by appropriate design reqirements covering debris ejection from engines and/or impact strength requirements for the airframe. |
Issued: 15-DEC-1988 | To: | G-BGJL (22) |
Aerosols with hydro-carbon propellants should be treated in the same way as other cylinders of flammable gas and their carriage on board aircraft controlled accordingly. |
Issued: 15-DEC-1988 | To: | G-BGJL (23) |
A requirement should be introduced to ensure that all portable oxygen bottles carried on board public transport aircraft are fitted with pressure relief valves and are stowed in thermally protected areas, preferably at low level. |
Issued: 15-DEC-1988 | To: | G-BGJL (25) |
The proposed requirement for cabin crew smokehood protection be extended to include training for crew donning and use during aircraft emergency evacuations associated with a fire and/or smoke threat during the evacuation. |

A research program should be undertaken to establish the effect of water mist/spray extinguishing systems on the toxic/irritant constituents of fire atmospheres. |
Issued: 15-DEC-1988 | To: | G-BGJL (28) |
The existing regulatory requirements governing the Evacuation Certification of public transport aircraft should be reviewed and amended to include: i) A demonstration of an acceptable evacuation time when the cabin is evacuated using half the total number of exits, disposed towards one end of the cabin; that end being chosen which represents the greatest restriction to passenger egress.; ii) Simulation of a defined dense smoke atmosphere within the cabin, existent from the initiation of the evacuation until its completion.; iii) All other sub-testing associated with cabin evacuation, including passenger aisle flow, the identification of exits and aperture egress rates, upon which design and configuration certification decisions are based, be conducted in the same simulated smoke atmosphere. |
Issued: 15-DEC-1988 | To: | G-BGJL (29) |
The design strength of the break-forward \'baulks\' fitted to the seats adjacent to overwing exits should be increased to prevent failure due to passenger pressure-loads on the backs of these seats. |
Issued: 15-DEC-1988 | To: | G-BGJL (3) |

Issued: 15-DEC-1988 | To: | G-BGJL (4) |
Consideration should be given to the requirement to fit an evacuation alarm permitting flight deck crew to instruct cabin crew to initiate an evacuation immediately, or if the aircraft is still moving to prime for an evacuation immediately the aircraft is brought to a halt. |
Issued: 15-DEC-1988 | To: | G-BGJL (6) |
The Civil Aviation Authority should continue to work with other regulatory authorities to define a mandatory international code of practice for identifying the appropriate method of promulgation for manufacturers\' safety information. This code should include a procedure for ensuring that, at the earliest opportunity, preliminary/advisory information should be followed up and superseded by appropriate Bulletins, Airworthiness Directives or manual ammendments. |
Issued: 15-DEC-1988 | To: | G-BGJL (7) |
If manufacturers are to continue to supply maintenance guidelines which require the operator and his regulatory authority to determine maintenance intervals, particularly for critical components, a re-evaluation should be undertaken of the methods employed to judge residual component lives, particularly following repair. |
Issued: 15-DEC-1988 | To: | G-BGJL (8) |
Direct fusion weld repair of circumferential cracks in JT8D engines combustor cans should be deleted from all approved Engine Overhaul Manuals, unless the safe life of the repaired can has been demonstrated for the anticipated overhaul/inspection period. |
