For the benefit of LARTSA and other whisperers out there - THE FACTS of this 'mid-air'

1 x R22 and 1 x R44, both parked by previous flyers.

The R22 had started its rotors and run through it preflight checks for a training flight. The mentioned CPL is currently doing his FI rating and was waiting for his instructor to join him. The instructor boarded the aircraft and they were just about to lift when a large BANG was heard followed by a heavy vertical vibration. The aircraft was immediately shut down.

It would seem that the R44 parked next to the R22 and due to depart on a training flight with an experienced instructor and their student had decided to start their aircraft and as the clutch engaged it swung the R44 main rotor in to the R22 blades.

Luck did have something to do with it because the R22 was just about to lift!

As for the Jetranger - not an over temp but an over torque to 116% - as recorded by the digital guages. The CPL mentioned by LARTSA was on board but was not P1 - the aircraft was being positioned by a fairly experienced turbine pilot.

The verdict for the 206 incident is an entry in vortex ring state at about 50ft possibly due to windsheer and the result was to try and recover as best as possible and as opposed to hitting the ground very hard the CPL elected to pull the lever at the last minute once some sort of recovery had been achieved.

The CPL has taken responsibility of the Over-Torque despite not being P1 as the situation should not have occurred.

MORs have been completed for the R22/R44 incident and the Engineers informed - so no skull-duggery i'm afraid!
