AMC 29.1585 Operating Procedures

• ED Decision 2018/007/R found in: CS-29 Amdt 10 - Large Rotercraft (Jan 2023)

AMC 29.1585 Operating Procedures ED Decision 2018/007/R [CS 29.927(c)](#_DxCrossRefBm1513259415) provides guidance for the completion of testing to simulate a loss of lubrication and on how to demonstrate confidence in the margin of safety associated with the maximum period of operation following loss of lubrication. This margin of safety is intended to substantiate a period of operation that has been evaluated as likely to be safer than making a forced landing over hostile terrain. Accordingly, the need to ‘Land as Soon as Possible’, which may include ditching where circumstances permit, should be reflected in the associated RFM emergency procedures. This can be supplemented with ’Land Immediately’ in the event of additional conditions to that of low oil pressure being present. Emergency procedures should identify the need to minimise the power that is used for yaw and accessories following a loss of oil pressure warning.
