Unsafe Condition
An unexpected reduction in fuel pump performance has been seen during testing of high life fuel pumps. Strip examination of these fuel pumps has identified that life related wear-out of the internal components is causing deterioration in pump efficiency. The effect of the loss of fuel pump efficiency is more pronounced on higher rated engines. This condition, if not corrected, could lead to reduced engine thrust, possibly resulting in reduced control of the aeroplane.
