Oman Hawk Crash. Crew ok

Heard a rumour that an Omani 2 seat Hawk crashed on landing at Masirah. One brake had full pressure indicated which they couldn't disipate. After staying straight for a few seconds the jet came off the side of the runway and the gear collapsed. Crew made a rapid egress; shaken not stirred.

Glad they were ok.

I remember that the Hawk pre-landing check calls for hyds of 3 twos, 2 zeros. What advice is there for getting rid of the residual pressure if you don't have 2 zeros?

Ask the instructor to take his feet off the brakes?? Worked every time for me.

Glad to hear the crew are ok.

Clearing a Hawk stuck brake - Can only think of pumping the brakes and cycling the handbrake - BUT NOT AT THE SAME TIME. If that doesn't do it , the Brake Control Valve is definitely knackered so do the riggers a favour and eject rather than trying to bring the thing back because it's a swine to change.

Seriously, I donít know what FRCís say but I really wouldnít try and land it, instant recipe for disaster.

It's not that bad! Just land on one side of the runway and wait for the tyre to burst. It'll be exciting but it won't kill you!

I had a stuck brake indication on the Hawk at Chivenor (aahh) many years ago. But plenty of fuel. So I flew round and round whilst the assembled experts gathered in the tower.

By selecting idle thrust and operating as many hydraulic services simultaneously as I could, I was pretty sure it was an indication problem. After burning down to min. fuel, I landed with one hand near the anti-skid switch figuring that if a tyre burst on touchdown, I'd minimise any swing towards the estuary by turning off the anti-skid and bursting the other.

All went OK; it was indeed an indication snag. Probably. But I shut down and asked to be towed back - this caused OC Fg Wg to moan as it upset his flying programme. Tough titty, Wally!

Bloody good idea, I like that.

A better idea - if you're sure it's not a problem with the gauge -might be to land with both brakes on and induce a double tyre burst. I did that once in a Lightning and it stopped exceedingly quickly - in a straight line.

The newer generation Hawks, 100 series, have an improved Anti-skid system over the T1 with spin-up protection. Apparently BAeS test pilots landed with the brakes on to test it in the early days (can anyone confirm that?). I guess it only works if both brakes are on!

Glad they walked (ran) away. Some new drop tanks needed I wager.
