A PILOT may have become "overwhelmed" when his plane lost power at an altitude of 500 feet, before crashing at Redhill Aerodrome.
David Marjason, a chartered surveyor from Oxted, was killed in the crash on August 28 last year while practising take-offs and landings in a microlight plane, which he owned as part of a four-man syndicate.
A report released by the Air Accidents Investigation Branch (AAIB) has attributed the crash to a "sudden power reduction" coupled with Mr Marjason's "relative inexperience" and lack of time to respond.
At no point during the crash did Mr Marjason – who had only qualified the month before his death – radio Air Traffic Control to report a problem.
The report said: "The initial action of a pilot experiencing a power loss should be to lower the nose of the aircraft to prevent it stalling.
"On this occasion, the pilot appears not to have lowered the nose after the power loss; the aircraft continued in a climbing attitude and decelerated, until it stalled."
It added: "The lack of any radio transmission after the power loss may indicate that the pilot became overwhelmed by the situation.
"Nevertheless, if the pilot had been able to lower the aircraft's nose before it stalled, he may have been in a position to maintain a safe airspeed and perform a forced landing."
Mr Marjason was practising touch-and-go landings – where a plane touches down briefly before taking off again – when he stalled during a takeoff and plunged into a nose dive from which he could not recover.
The wreckage meant AAIB investigators could not assess every part of the engine and the report, released last month, could not establish a definitive cause for the power loss, which happened as Mr Marjason took off from a successful touch-and-go landing.
It noted, however, that Mr Marjason had attempted a previous touch-and-go landing which he had converted into a full landing after appearing to approach from too high an angle and striking the ground, which could have damaged the propellor.
After taking off from this incident Mr Marjason completed an "uneventful circuit" before touching down and taking off as planned, but as the plane reached an altitude of about 500 feet, witnesses heard the engine falter.
The plane then decelerated while continuing to climb, it rolled slightly left before the right wing dropped and the plane fell into a nose dive.
Sudden
The report concluded: "The sudden power reduction, the pilot's relative inexperience and the limited time available to react appropriately are likely factors in the pilot not lowering the nose before the aircraft stalled.
"There was then insufficient height available for the pilot to effect a recovery from the stall before ground impact."
A post-mortem examination found Mr Marjason, of Hamfield Close, died of head and chest injuries.
He ran his own firm of chartered surveyors, Marjason & Associates, as well as playing the second horn in Oxted Band.
