(5) Torque each fuel hose fitting in accordance with the Standard Torque Tables in the latest
revision of the Service Table of Limits - SSP-1776.
(6) Make sure that the fuel hoses are securely held in place, attached to the engine (to
dampen vibration during flight) with the necessary serviceable cushioned clamps and
hardware. Install clamps on the fuel hose as per the following guidelines:
(a) Make sure each serviceable clamp securely supports the fuel hose to prevent fuel hose
movement due to vibration, friction, or motion frequencies during flight. Do NOT
use plastic tie straps as clamps.
(b) Install serviceable cushioned clamps on the fuel hose. Make sure the cushion is not
missing and is intact, and completely covers the fuel hose diameter. If cushions are
deteriorated or missing, replace the clamp with a new clamp with the cushion intact.
(c) Refer to Figures 5 and 6 which show how the fasteners are to be installed on P-clamps
and L-shaped clamps.
(d) Make sure the clamps are securely attached to support the fuel hose and to prevent
movement from vibration or motion frequencies.
(e) Torque the fuel hose connections in accordance with the Standard Torque Tables in
the latest revision of the Service Table of Limits - SSP-1776.
CAUTION
(7) Complete the operational ground check in Chapter 72-00 after all maintenance is
complete. Look for fuel leaks at the fuel hoses and connections during engine operation.
Identify and correct the cause of any fuel leak. There must not be any fuel leak when the
engine is returned to service.
(8) Remove the fuel collection container and dispose of the fuel in accordance with
environmental regulations.
