SUMMARY OF REQUIREMENTS AND BRIEF DESCRIPTIONS
Varsity WF.415 was delivered as a standard aircrew training aircraft
and had been in storage at No. 48 MX., Hawarden, for a considerable
period.
Under the contract the College was required to:-
1. Prepare the aircraft for delivery flight to Cranfield,
2. Carry out a Major Inspection.
3. Embody all outstanding modifications as required by R.T.O.Vickers.
4. Convert the aircraft from military to civil category.
5. Embody the required special modifications (listed in Part 4,Section 1).
6. Maintain the aircraft during a period of proving flights and.
A,R,B. Test Flights.
Prior to the delivery flight a discussion took place with the S.T.O.
Hawarden. On the basis of this meeting a list of minimum requirements
was raised by the Chief Inspector to fitness for flight to a one flight
standard. A party of College employees was sent to prepare the aircraft,
the operation taking five days.
On arrival at Cranfield the aircraft underwent an acceptance check
and was completely stripped. The Inspection Schedule and. Varsity
Modification requirements were raised.
During the period required for the design of special modifications,
the Major Inspection was carried out and the standard modifications
embodied. It was decided that the sections of the aircraft affected by
the special modifications (mainly cabin and cockpit area) would be
inspected for defects and that the major inspection would be carried
out on completion of these special modifications. This ensured that the
spares required in these sections would. be readily available and the major
inspection, when carried out, would not uncover any serious defects.
To avoid unnecessary load on the Design Department it was decided that
during this period certain of the special modifications should be embodied
to Flight Department drawings approved by Design The work was confined
to non-structural parts. This permitted completion of a considerable
number of the special modifications during overhaul, thereby releasing
skilled man power for the more extensive special modifications as they
were designed. During the period, close liaison was maintained with
Design Department to ensure that equipment required would be available on
receipt of drawings, thus avoiding, as far as possible, delay due to
protracted delivery dates. |
