How USAF is Tackling Hypoxia-Like Incidents in its T-6, Fighter Fleets

The Air Force Physiological Episodes Action Team has recommended the service stand up two new program offices to help it monitor and reduce the number of hypoxia-like incidents in its trainer and fighter fleets. The move comes as both the Air Force and Navy work to overhaul the On-Board Oxygen Generation systems in their T-6 trainer fleets, following a spike in such incidents and an extended grounding last year.

T-6 hypoxia problem solved, Air Force announces

The rash of hypoxia-like problems in the Air Force?s fleet of T-6 Texan II trainers was primarily caused by fluctuating concentrations of oxygen in the cockpit, the service said Thursday.

Air Education and Training Command said in a release that the Air Force will start putting a series of fixes in place to correct the problems. These fixes will include redesigning the oxygen system in the T-6, adjusting oxygen levels in flight, and increasing maintenance on the On-Board Oxygen Generating System, or OBOGS.

A six-month study conducted by AETC and Air Force Materiel Command, uncovered the problem with varying oxygen concentration levels, which AETC described as the ?major factor in unexplained physiological events? affecting T-6 pilots, AETC said. Experts from the Navy and NASA also assisted with the study.
