Fuel leaks and pre-flight inspection
 

Content Responsibility: Icelandic Transport Authority

1 Introduction

Incidentally, the Icelandic Transport Authority draws the attention of pilots and maintenance bodies of small aircraft to the following:

Recently, a pilot was forced to land his plane after its fuel tanks had emptied due to a leak in a fuel filter drain tap. Some aircraft types are equipped with a fuel injection valve, which, according to the flight manual, shall always be "open" except in emergency situations or when maintenance is to be carried out on the fuel system in front of the firewall. This valve should be wire-bound for safety in the open position.
The wire shall be of a type that can be easily broken, if needed. In this case, the wire was torn.

If you notice fuel leaks during pre-flight inspection originating in an area behind or in front of the firewall, brake the safety wire and close the said injection valve. The leak shall be examined closely and the fault shall be repaired before the airplane is declared airworthy again.

2 To flight schools and pilots

2.1 Flight Manual

Instructions contained in the Flight Manual (Operations) for aircraft shall be followed. The pre-flight inspection for the above aircraft design includes verification by the pilot that the fuel valve is open and wire-secured. Pilots may never close this valve unless leakage is detected on the ground and in a state of emergency during flight. If, for some reason, the valve must be closed, the aircraft becomes non-airworthy until it has been declared airworthy again by an aircraft maintenance technician who holds an appropriate authorisation.

2.2 Logbook

Accidents have occurred because the pilot next in line to fly the aircraft did not receive the necessary information.
Therefore, it is strongly recommended to the owners/operators of private aircraft which do not already have logbooks in their aircraft that they acquire such a book. This is primary in the case where two or more persons fly the same aircraft. After each flight, records must be made into the technical logbook on any malfunctions or defects that may have occurred in that flight as well as other information that could be of help to those who will fly the aircraft next and the aircraft maintenance technician(s) responsible for maintenance and repair.
