What happened
On 18 December 2012, a Pegasus Quik microlight, registration G-CEML, was conducting a local flight from a private airstrip near Warrington, Cheshire. The weather conditions were favorable, characterized by calm winds, clear skies, and good visibility. The pilot, who was flying to regain currency after a period of inactivity, opted to perform a glide approach for an easterly landing.
While the pilot was aware of a set of power lines crossing the approach path and had successfully navigated around them, a second set of lines remained undetected. As the aircraft entered the flare for touchdown, it struck these wires. The impact caused the aircraft to pitch upward sharply before descending to the ground. The collision severed one of the three 11kV distribution cables, causing a power disruption to nearby properties.
The investigation
Investigators examined the aircraft and the landing site, which included a secondary, smaller grass area used when the main strip is waterlogged. The investigation established that the pilot had been maneuvering for takeoff in an unfamiliar area, which diverted his attention laterally.
It was noted that the second set of power lines lacked conspicuous supporting poles, making them difficult to identify. The investigation also looked into the pilot's flight experience and the specific flight profile, noting that the steeper angle required for a glide approach may have contributed to the oversight.
Findings
- The pilot sustained serious injuries, including broken ribs and various lacerations.
- The lack of conspicuity of the power lines, due to the absence of obvious supporting poles, played a significant role.
- The pilot's attention was divided by the requirements of maneuvering for takeoff in a relatively new operating environment.
- The steeper descent angle associated with the chosen glide approach likely hindered the detection of the wires.
