PA30 – Camden

Training and EMG procedures:

In training emergency procedures, the following must be followed:

ATO Requirements:
GEN 1 Only emergency and abnormal systems failures listed in the test aircraft Pilot Operating Handbook are to be simulated by a prescribed ATO during the flight component.
GEN 2 A prescribed ATO or a prescribed person must not introduce simultaneous multiple unrelated simulated emergency or abnormal situations during the flight.
GEN 3 After a simulated failure, the prescribed ATO or a prescribed person must ensure the aircraft is configured back to a normal operating mode before another simulated failure may be introduced except where the simulated failures are linked (e.g. electrical failure leading to a flapless approach and landing).

Just remember, not following the AFM could well result in:

PA30-160 EFATO at Camden

FACTUAL INFORMATION

On 23 December 2010, at about 0832 Eastern Daylight-saving Time1, a flight instructor and student pilot in a Piper Aircraft Corporation PA-30 (Twin Comanche) aircraft, registered VH-EFS (EFS), departed Camden Airport, New South Wales on a training flight.

The student was in the process of obtaining a command (multi-engine) instrument rating. The instructor had planned for the flight to include a number of instrument approaches and simulated engine failure exercises (asymmetric operations)2.
The pre-takeoff checks were completed by the student who also conducted a take-off safety brief, which included reciting the procedures for responding to an engine failure.

After takeoff, the student completed his after-takeoff checks. The instructor contacted air traffic control and requested approval to conduct asymmetric operations; the request was approved.
1 The 24-hour clock is used in this report to describe the local time of day, Eastern Daylight-saving Time, as particular events occurred. Eastern Daylight-saving Time was Coordinated Universal Time (UTC) +11 hours.
2 The terms simulated engine failure and asymmetric operations are used interchangeably in this report.

Shortly after, at about 400 ft above ground level (AGL), the instructor directed the student, ‘practice engine failure’. The instructor, covering the engine mixture controls (Figure 1) with his hand, moved the mixture control on the right engine close to, or at the idle cut-off position. The instructor continued to position his hand on the mixture control.

The aircraft crashed.
