GIPSY MAJOR MK. 8
GIPSY MAJOR M K.8
As the original Gipsy Major Mk. 8 engines (pre-mod. 1685) were fitted with Hoyt white metal bearings and all the Gipsy Major 10 Mk. 2 engines have the Vandervell main bearings, civil
approval of the Gipsy .M. ajor Mk. 8 was neither sought nor obtained.
With increasing numbers of Royal Air Force Gipsy Major Mk. 8 engines becoming available in the civil market, the Air Registration Board has agreed that this type of engine can be used in civil aircraft subject to the following provisos :-
- The military log card or log book must be available.
- Before the engine may be used, the operator must comply with the current requirements of Air Registration Board Notice to Licensed Aircraft Engineers No. 16.
- On transfer of the engine from the Royal Air Force, a civil type log book must be raised and all relevant entries made in it. The log book may only be raised by the Inspection Department of an organisation approved for the overhaul of de Havilland Gipsy engines, or by a ‘ D’ Licence engineer in this category.
- The engine type must be recorded in the log book as “Gipsy Major 10 Mk. 2” and the engine name plate must be altered to accord with this nomenclature.
- The log book must be endorsed to the effect that only fixed-pitch propellers may be used on the Gipsy Major Mk. 8, or 10 Mk. 2, engines with Hoyt white-metal main bearings ; modification 1685 introduced Vandervell bearings to Gipsy Major Mk. 8 engines.
The instructions and information given in this handbook for the Gipsy Major 10 Mk. 2 are equally applicable to the Gipsy Major Mk. 8 having regard to· the modification standard of the engine.
