Aircraft Details: SA341G YU-HMC cn.1136

Date: 14th July 2018

Location: Enfield, Greater London

Accident Summary:

While trying to reposition his helicopter from one part of his garden to another, the pilot perceived that the engine had lost power. He tried to return to the takeoff site but the helicopter came down about 20 metres short and rolled onto its side. The helicopter was destroyed by a post-crash fire. The cause of the reported loss of power could not be determined.

Synopsis:

Although it was a hot day with calm wind, the helicopter was 276 kg below its maximum takeoff weight so it should have had sufficient performance for the taxiing manoeuvre the pilot undertook. It is possible that the airpath to the centrifugal compressor had accumulated deposits during operation which led to a lower compression rate and a higher temperature operation. This, combined with the hot outside air temperature, could have led to a T4 exceedance, turbine damage and a consequential loss of power, leading to the accident. However, it is also possible that the T4 exceedance occurred during the post-impact fire and that some deposits were ingested while the engine continued to run on the ground, with the helicopter on its side.

Accident Date: 16th January 1991
Operator: Royal Navy
Model: SA341C
Registration: XW886
C/N: WA1157

Accident Summary

On 16th January 1991 an SA341C Westland Gazelle belonging to No. 705 Naval Air Squadron at Culdrose crashed into a field in the Goonhilly Exercise area, near Predannack, Cornwall after the pilot lost yaw control during a semi-wing-over manoeuvre when avoiding another Gazelle. The pilot escaped from the wreckage but was seriously injured.

The pilot was was recovered by a Sea King helicopter and then sent to the AIU at Lee-on-Solent by road.

The aircraft had been flown into an undefined area of the flight envelope known as the 'Fenestron Vortex'. The Fenestron, a shaft driven 13 blade fan, replaces the conventional tail rotor.

This was the twelfth accident to a British Forces Gazelle attributed to this effect.

Accident Date: 8th March 2011
Operator: Honister Mine
Model: SA341G
Registration: HA-LFB
C/N: 1074

Accident Summary

On the evening of 8th March 2011 at approximately 7 pm, a Gazelle helicopter (registration HA-LFB), crashed while attempting to depart from the Honister slate mine in Cumbria. Having lifted-off, the helicopter was flown at low level and slow speed within the valley immediately below it's point of take-off. In what appears to have been an attempt to negotiate a departure route in reduced visibility conditions, the helicopter's main rotor struck the side of the valley resulting in the destruction of the aircraft and the fatal injury of the pilot.

The pilot’s ability to maintain a safe flight path may have been affected by diminished situational awareness or a loss of control, and there was evidence of poor lighting and weather conditions that might have contributed to these difficulties, especially if the helicopter had inadvertently entered cloud. In addition, canopy misting, distracting illumination of cloud by the landing light or strobes, turbulence, and windshear are factors that may be associated with the prevailing conditions but for which there was no direct evidence.

The pilot’s difficulties may have been compounded by the helicopter’s handling characteristics at low speed, the degraded performance of the yaw damper and the possibility that the helicopter entered vortex ring. There was no evidence that the pilot had received training in night flight. His decision to depart in the prevailing weather conditions, and from a site with no cultural lighting, suggested either a lack of awareness of the inherent risk or an acceptance of the risk.
