Suggest you look at the following link - it appears that the use of airbrakes could prove fatal in the landing configuaration and I recall an accident to the vintage pair where this was the possible cause.

There was also the problem of "The Phantom Dive". In the T7, and maybe in the single seaters, you never selected airbrakes out with the gear and flap down otherwise the airflow over the back end effectively ceased and the thing just went down. If I remember correctly, this problem was made worse by the close proximity of the airbrake and the flap levers, both in the same place and both acting in the same way.
