Taff reports on this week

XH558's 2017 service - Report #2

Service work on XH558 is continuing with Taff Stone (Chief Engineer) connecting a hydraulic test rig to the aircraft to enable the functional check of the bomb-bay doors and to ensure they were open for the last hangar event, which was a wedding last week. Our thanks to 2Excel Aviation for allowing us to return XH558 to Hangar 3 for a few days to allow this event to be honoured. 
XH558 is now back in Hangar 1.
Taff is over half-way through the servicing having carried out inspections and checks on numerous electrical systems and wiring, with pictures in the feature below. Other tasks have been completed such as inspections on the engines and jet pipes covered in the last newsletter, along with the servicing of the Airborne Auxiliary Power Plant (AAPP). 
This week we also had technicians visit the hangar for the ultrasonic checks on the main undercarriage and eddy current check on the engine low pressure compressor blades, sponsored and carried out by Aerospace NDT free of charge!

Here is an photo-update on recent work.
