US16LA Ejection Seat for T-6 Texan II
The JPATS (Joint Primary Aircraft Training System) is designed to train students in basic flying skills and is common to the U.S. Air Force and Navy. Designated the US16LA, this lightweight ejection seat is designed for training aircraft, such as the T-6 Texan II.
It optimises the pilot field of view, improves comfort and pilot efficiency, and provides increased reliability and maintainability. With the Mk16 lightweight low-speed seat, ejection performance is optimised throughout the escape envelope, from zero height at zero velocity in a near level attitude through to 370 knots. It is designed to accommodate a very wide size and weight range.
The T-6 Texan II is currently operated by 7 different countries. These include Canada, Greece, Iraq, Israel, Mexico, Morocco and USA. Since the first JPATS delivery in 1997, over 1,600 seats have been delivered worldwide. A total of 11 aircrew owe their lives to the US16LA JPATS Ejection Seat.
Here’s what some of our ejectees had to say about our US16LA ejection seat:
“I would like to extend my gratitude and appreciation of your equipment, as I personally feel that it saved my life.” – 2nd Lt. Francis D. K. Lessett, T-6 Texan II, US16LA ejection seat, 2nd April 2010.
“Thank you so much for your outstanding work! Every person I know is thankful!” – Nicholas Brumgard, T-6 Texan II, US16LA ejection seat, 24th September 2010.

US16LA Ejection Seat for T-6 Texan II
- Seat firing handle pulled causing seat initiation cartridge to fire
- Interseat sequencing system initiated initiated
- Harness retraction unit operated
- Primary cartridge fires, bottom latches engage, top latches disengage seat rises up rails
- Canopy fracturing MDC initiated
- Aircraft services disconnected
- Leg restraint lines draw back and restrain aircrew’s legs
- Secondary cartridges fire as seat rises
- Multi-purpose initiators fire
- Underseat rocket motor fires
- Leg restraint lines become taut and rivets shear, freeing lines from floor brackets
- Emergency oxygen supplied to aircrew
- Barostatic time-release unit (BTRU) mechanism set to operate when altitude and g-load conditions are satisfactory
- Manual override handle lock released
- Drogue and bridle deployed, stabilise and decrease velocity of seat
- Barostatic time-release unit (BTRU) monitors the altitude and g-load conditions
- Above 15 000 ft
- Seat falls, stabilised by drogue
- Emergency oxygen supply continues
- Below 15 000 ft but above 8000 ft
- Seat falls, stabilised by drogue
- Emergency oxygen supply continues
- G-restrictor prevents operation of time-release mechanism until g-load is satisfactory
- Below 8000 ft
- Time-release mechanism operates, cartridge fires (If BTRU fails manual deployment also available by pulling manual override handle)
- Cartridge of headbox deployment unit fires
- Parachute container (headbox) deploys
- Drogue bridle released
- Sear of time-delay unit (TDU) operated
- After delay, TDU fires
- Upper and lower harness to seat locks released
- Leg restraint lines released
- Parachute container (headbox) separates from main parachute and is pulled clear by auxiliary parachute
- Sticker straps momentarily hold aircrew in seat
- Main parachute develops, lifts aircrew and survival pack from seat and pulls sticker clips from clips causing aircrew and seat to diverge
- Aircrew and survival pack (attached to aircrew) separate from seat
- Pulling survival pack from seat causes automatic deployment unit (ADU) cartridge to fire (if seat to AUTO)
- If set to MANUAL aircrew pulls handle to manually deploy
- ADU operates, lowers survival pack on drop line below aircrew
- Personal locator beacon operates, automatic liferaft inflation unit (ALIU) armed
- Normal parachute descent follows
