Grenchen Plane Crash: Parachute Triggered Fatal Descent

A fatal plane crash near Grenchen, Switzerland, in February 2024, has been attributed to an accidental deployment of a parachute by a skydiver during a jump. The incident resulted in the death of the pilot and has prompted a review of safety protocols, though no immediate changes are planned.

The Sequence of Events

On February 18, 2024, a Pacific Aerospace PAC 750XL aircraft was conducting a skydiving operation near the Grenchen airfield. Eleven skydivers and one pilot were on board. Nine skydivers had exited the plane when the emergency parachute of one of the remaining two skydivers unexpectedly opened during the exit process.

The sudden deployment pulled the skydiver from the aircraft and into the plane’s empennage, specifically the tail section. This impact completely severed the empennage, rendering the aircraft uncontrollable and initiating a steep descent. Approximately 90 seconds later, the plane crashed in a field southwest of the Grenchen airport.

Pilot’s Fate and Skydiver’s Condition

The pilot did not have a parachute and was unable to escape the rapidly descending aircraft. The skydiver whose parachute unexpectedly opened survived the incident with minor injuries. An investigation by the Swiss Safety Investigation Board (Sust) determined that the pilot’s lack of a personal parachute contributed to the fatal outcome.

Did You Know? In 1998, a similar incident prompted a recommendation that pilots wear parachutes during skydiving operations, a suggestion that was never formally adopted.

Investigation Findings

The Sust investigation found no technical faults with either the aircraft or the parachuting equipment. The automatic activation device on the skydiver’s emergency parachute did not deploy, leaving the exact cause of the accidental activation undetermined. Investigators noted that movements within the confined space of the aircraft cabin could inadvertently affect equipment.

Expert Insight: The investigation highlights the inherent risks associated with skydiving operations and the critical importance of pre-jump equipment checks. While the Sust’s focus is on prevention, the incident underscores the potential consequences of even minor equipment malfunctions or unintentional activations.

Potential Future Steps

While the Sust’s report does not issue new safety recommendations, it is possible that aviation authorities or skydiving organizations may re-evaluate existing protocols. A possible next step could involve a review of training procedures for skydivers and pilots, emphasizing the importance of equipment checks and emergency procedures. It is also likely that discussions will occur regarding the potential benefits of making pilot parachutes mandatory during skydiving operations.
