Aviation safety issues and actions
Recommendation issued to: Cessna Aircraft Company
|Date issued:||09 October 2007|
|Safety action status:||Closed - No Action|
|Background:||Why this Recommendation was developed|
The Australian Transport Safety Bureau recommends that Cessna Aircraft Company, consider revising the Cessna 208 series aircraft Pilot Information Manual for emergency procedures on chip detector and pilot warnings.
|Response from:||Cessna response|
Cessna Aircraft Company responded to this proposed safety recommendation (draft recommendation F) in the ATSB draft report by stating:
The ATSB does not accept Cessna's comment in relation to the information contained in the pilot's emergency procedures. While acknowledging that the pilot is best placed to evaluate any abnormal situation, the emergency procedures statement "if engine gauges are normal, proceed to destination..." can be misleading if the number-1 engine bearing is becoming distressed. This investigation has shown that this process can take only a few minutes from chip detector light illumination to complete engine failure.
It is the ATSB's view that the Cessna emergency procedures should consider this scenario and include a statement such as "land at the nearest suitable location" irrespective of engine gauge readings. This does not mean the pilot should carry out an off airport landing as stated in the Cessna response. As such, the ATSB now formally issues safety recommendation R20070018.
