Aircraft Type and Background


MAEE*  Saunders-Roe A.36 Lerwick Mk I  /  L7248 (Prototype)


* Marine Aircraft Experimental Establishment (WWII Top Secret Establishment).


The Lerwick featured here (L7248) was the first of its type to be built. The type was equipped with two Bristol Hercules engines and three powered turrets.


Saunders-Roe (Saro) Lerwick L7248 was the first of three prototype aircraft. The aircraft suffered from several design defects, including instability on water and in the air. Nevertheless, in spite of this and other problems, and because of the urgency of the situation, Lerwicks were pressed into service with 209 Squadron RAF based at Oban (Ganavan Sands) during 1940.


Twenty-one Saro Lerwicks were built. However, while still being delivered new to RAF Squadrons, the type was declared obsolete and were replaced by Consolidated Catalina flying boats.






Aircraft Accident Details


The Lerwick featured here was the first prototype aircraft, L7248. The aircraft was on a Calibration Test from MAEE Helensburgh. At the time, this was a Top Secret establishment that had been relocated on security grounds from its previous base at Felixstowe (Folkestone, according to some sources).


The aircraft had taken off from Rhu, a few miles from Helensburgh, when it developed an engine fault. It then flew low over the loch (Gare Loch), hit telegraph wires, and crashed above Faslane. The aircraft was smashed up, apart from the tail. The area is an oil depot, Greenfield Camp, OS Sheet 56 / 246901.





Inquiry Summary


The detail says the pilot was inexperienced on type. The starboard engine failed in flight, the aircraft was unable to maintain height on one engine and flew into a hill at Faslane, Shandon.


Both engines were sent to Bristol for strip examination but nothing was found to account for the failure. It was therefore assumed that extractor control trouble may have been experienced. It was noted by both AIB and OC that the handling characteristics of the Lerwick had never been satisfactory when flying with one engine feathered and there is little doubt that with failure of either power plant under similar circumstances the pilot would be in a most difficult situation.


Full details of this appear in UK Flight Testing Accidents 1940 to 1971 from Air Britain.


The aircraft was very new to the RAF and being rushed in on account of the increased U-Boat threat. Only 21 were manufactured: 3 with the MAEE and the rest to 209 Squadron, a Coastal Command Squadron based at Oban. It was quickly overtaken by the Sunderland which re-equipped the Squadron as Lerwicks were still being delivered.
