  • Gannet Electronics
    Gannet Electronics A Summary of the Electronic Equipment Fitted to early Model R.A.N Gannet A.S.1 Aircraft Prepared by David Mowat Ex-L.R.E.M.(A) 21st. August 2003 Page 1 Page 2 GANNET ELECTRONIC EQUIPMENT Introduction The ‘Heart’ of the Gannet as a Weapons System was its Electronic Equipment. It contained a comprehensive range of electronic equipment to enable it to perform the various roles for which it was designed. Its Primary Role was to detect, locate, and destroy enemy submarines. For this Role, the Aircraft was fitted with a Search Radar and Sonobuoy Systems. Other electronic systems were also installed for Communications, both internal and external, and Navigation. The various equipments were allocated an ‘Aircraft Radio Installation’ (ARI) number, which specified the actual equipment used in each installation. These may vary between aircraft depending on the role that the particular aircraft was to perform. A cross- reference List of ARI’s is shown at Appendix ‘A’. The various equipments can be grouped into four major categories as follows: a.! Communications b.! Navigation c.! Warfare Systems d.! Stores Communications Equipment The Communications Equipment was used to enable the crew to talk to each other (internal communications) and other aircraft, ships or bases (external communications). They are as follows: a.! Audio Amplifier Type A1961 The Type A1921 was used to amplify the Microphone outputs from the three crew members and feed it back into the earphones. It was located on the port side of the rear cockpit at about seat height just forward of the Radio Operator.

SUMMARY The aircraft was operating East African Airways Service flight number EC037 from Dar es Salaam to Nachingmea with an unscheduled refuelling stop at I1twara with 3 crew and 16 passengers on board. The flight from Dar es Salaam was uneventful and an approach and landing was made onto runway 19. After touch down the aircraft swung to the left and then to the right, after which it left the runway where both main landing gear assys collapsed causing substantial daLage to the centre section and nacelle structure. The report concludes that the most probable cause of the accident was the failure of the pilot to initiate corrective action to prevent the aircraft from turning off the runway. 1.1 HISTORY OF THE FLIGHT: The aircraft departed Dar es Salaam with three crew and 16 passengers.

However, the Bureau fully recognises that the implementation of recommendations arising from its investigations will in some cases incur a cost to the industry. Consequently, the Bureau always attempts to ensure that common sense applies whenever recommendations are formulated. BASI does not have the resources to carry out a full cost- benefit analysis of every recommendation. The cost of any recommendation must always be balanced against its benefits to safety, and aviation safety involves the whole community. Such analysis is a matter for the CAA and the industry. ISBN 0642 193959 June 1993 This report was produced by the Bureau of Air Safety Investigation (BASI), PO Box 967, Civic Square ACT 2608. The Director of the Bureau authorised the investigation and the publication of this report pursuant to his delegated powers conferred by Air Navigation Regulations 278 and 283 respectively.
