Year Question Response
1998 OEM Letter: Recommends against routine use of the EFCU.
Nil
2005 ASOR Recommendation: investigate the frequency with this emergency system is used in every day training flights, whether it was designed for such a purpose and if so what sort of maintenance schedule is appropriate
Rejected
2010 ASOR: The use of airborne EFCU for training at 2 FTS be reviewed for compliance with DI (AF) OPS 3-1, which states that Airborne Emergency Training is to be conducted only where there is a clear benefit and minimum risk
WASO is developing an EE500 template for recording EFCU use.
2010 SPO Investigation: 70% of failures world wide occurred with RAAF aircraft. Feedback from Pilatus was that the EFCU should only be for emergency use and not training.
Log use of the EFCU for training purposes, to assist in determining the number of failures
2014 OEM Letter: Recommends against routine use of the EFCU.
Nil
History: Routine use of EFCU

Recommendations
37
• Beermullah airstrip maintenance (enduring) • Other emergency airstrip maintenance (enduring) • Use of airstrips in planning • 2FTS SI update (airstrip layout)
• EFCU Actuators, ensure within specification
• Non-emergency use of EFCU Toggle
• Awareness regarding surge ‘risk-factors’ • Awareness regarding EFCU Toggle + Surge scenarios

Key learning outcomes
38
• ASRs: Actions must address recommendation
• Using equipment outside of intended use. Make sure the risk has been assessed and accepted
• Question organisational norms
