Investigation Reveals Fatal Oversights in Alaskan Airman’s Death

A recent investigation by the U.S. Air Force has highlighted critical lapses in maintenance protocols that led to the tragic death of a young airman at Joint Base Elmendorf-Richardson, Alaska. The report, released by the Air Force Aircraft Accident Investigation Board on November 6, outlines several factors contributing to the fatal incident involving Staff Sgt. Charles Crumlett on March 15, 2024.

Crumlett, aged 25, was a weapons load crew chief assigned to the 90th Fighter Generation Squadron. He had been stationed at the Alaskan base for just one month prior to the accident. The airman enlisted in 2016 and completed his training as a weapons load crew member the following year. At the time of the incident, he was engaged in maintenance on an F-22 Raptor, a role that required both academic and hands-on training.

The investigation revealed that the maintenance team was conducting adjustments to the restraint fitting on the aircraft’s right configurable rail launcher (CRL) when Crumlett sustained a fatal head injury. The report indicates that the CRL was retracted while Crumlett was still in a hazardous position, underscoring a critical failure to follow established safety protocols.

Key Findings from the Investigation

The report identified several human factors that contributed to the mishap. Notably, there was a lack of line-of-sight between the cockpit ladder and the right side weapons bay. This visibility issue, combined with a failure to ensure all personnel were clear before retracting the CRL, created a dangerous situation. Investigators pointed to a failure in supervisory oversight, stating that proper direction and awareness were not maintained during the maintenance process.

Moreover, the investigation noted that the team was performing multiple tasks simultaneously. This multitasking led to confusion and a lack of coordination among team members. The report highlighted a proficiency level challenge, as the team was not frequently engaged in such tasks, which contributed to the incident.

Compounding the issue, there was a widespread misunderstanding regarding the function of the “safe switch” for the side weapons bay. The investigators noted that many team members erroneously believed that activating this switch would secure both the bay doors and the CRL. Instead, the switch only secured the doors, creating a false sense of security that may have led to reckless behavior.

Communication Breakdowns and Environmental Factors

In addition to procedural failures, the investigation found that communication issues played a significant role in the tragic outcome. The enclosed workspace, coupled with the operation of an auxiliary power unit, necessitated double hearing protection for the team. This environmental factor limited verbal communication, forcing team members to rely on nonverbal signals.

A thumbs-up signal from an airman was misinterpreted as an indication that it was safe to retract the CRL. Unfortunately, this led to Crumlett being positioned in the right-side weapons bay at the moment of retraction, resulting in the fatal injury.

The findings of this investigation serve as a sobering reminder of the importance of stringent adherence to safety protocols and clear communication in high-stakes environments. As the U.S. Air Force continues to address these issues, the hope is that such tragedies can be prevented in the future, ensuring the safety of all personnel involved in aircraft maintenance operations.
