The AIIB has just published its report on the accident where L39 G-BZVL ran off the end of runway 06 at Duxford onto the M11 last June.
A friend of mine, who was in the front seat died after unsuccessfully ejecting.
It seems there was a brake failure, but no obvious cause, though a number of possibilities are suggested which could be the reason for it.

raising the flaps soon after landing is to kill the lift produced by them at slow speeds during the landing. and is not something that is generic to the L39 .
the L39 nose does need to be planted relatively hard to ensure the WOW switch makes and allows the brakes to operate.
someone told me the reason for the switch was that pilots training on the L39 had a habbit of coming in nose high and applying the brakes hard which slammed the nose down causing damage so the WOW switch was introduced to ensure all wheels were on the deck before braking

Erm interesting – the flap position in theory could affect the weight
and traction but could also affect the attitude of the nose in relation to the ground

Might have been linked to the need to get the nosewheel on the ground for braking to be effective.

Perhaps the reduced lift is a factor – it means more weight on the wheels, so more traction…

I find it interesting the note on the ‘short stop’ landing procedure where they mention retracting the flaps – I cannot see what you would gain from that when aerodynamic drag is surely desirable?
