    While not an approved document the pictures show extracts from a Smiths catalogue which gives technical descriptions of their instruments (using the Smiths codes of 78RV for the indicator and 54MV for the generator) and generic installations.

    Hope it’s of use.

    Hi there,

    I have the Sec/ref number shown in the first pic as a shoulder strap as shown in the attached picture extract from AP1086 Sec 15A, if there are any more numbers on the item then post them and I’ll see what else I can find.

    Hope that helps

    No Sec 10B here either! But Sec 5L shows that 9959801 has a ‘special’ cap (no other cap details), hopefully a picture should appear here!

    It’s probably worth having a browse through CAA CAP562 Civil Aircraft Airworthiness Inspection Procedures Leaflet 61-10, although it doesn’t give a full list of propellers produced it does have a good list for ‘current’ civil UK manufactured aircraft.

    in reply to: Type M Ignition Suppressor code. #839191

    Participant

    Hi there,

    I had a quick look through Sec 5UA,UB,UC,UD& UE but couldn’t find any reference to suppressors.

    I did however find a Type M radio interference suppressor is Sec 5C and 5CY, sec/ref 5C/932 and 5CY/932, is this what you’re looking for? Dimensions are listed as 7.7″ x 4.1″ x 1.7″ weight 1.62lb

    Sec 5CY (Apr 1955) has a note saying ‘for ignition coil on Vulture engine’ but the earlier Sec 5C (Feb 1945) listing doesn’t.

    Hopefully that’s of some help!

    Regards

    From what I understand DTD904 has been superseded by DEF-STAN 03/19 which can be found here:
    ftp://ftp.iks-jena.de/mitarb/lutz/standards/dstan/03/019/00000200.pdf

    It may also be useful to browse through QQ-P-416 which is the American specification for cadmium plating.

    Not having seen DTD904 but having had experience of getting equipment cadmium plated (and also carrying out brush cadmium plating, which is qualified to QQ-P-416, to various specifications inc Dowty,Fokker, Boeing) most of the equipment used is the same and to a greater extent the vendor’s specifications are based upon the national specification with maybe different inspection criteria.

    Hope that helps

    Hi Andy,

    I have a Feb 1952 copy of AP1086 Book 3 Part 2 Sec 5B, please see attached picture of the first page.

    Although the listing does generally detail what aircraft/engine the cable was fitted to there doesn’t appear to be any breakdown for connector ident etc, the drawing numbers are provided for most assemblies and this would be where the detail parts would be found.

    If you let me know the Sec/ref numbers of the items you’re looking at/for I’ll see if they’re in this edition.

    Regards

    Yes, disposal legitimately of this stuff can be a problem so best to move to others who can use it.

    The Jaguar project at Bentwaters has benefited with a fair bit of POL to help them out.

    If this stuff is any use Mike I’ll add it to the lot, there’s only one can though.

    Hi there,

    Not sure if this is the info required and have only had a quick look but have found AP1275A Vol 1 Sec 15 Ch 9 relating to Mk1 and 2 brake pressure gauges.

    Hopefully there should be a copy embedded here!

    The pin appears to be located inside an aluminium bronze (spec DTD197A in old money but now B23) bushing which is a shrink fit into the aluminium casting/forging, so the pin will rotate within the bush.

    Lack of lubrication may well be some of the issue, as not only does it lubricate the joint it also keeps moisture at bay if done on a regular basis. There is a reason why a re-greasing of landing gear is called up after a pressure wash (if it is allowed at all, depends on operator and advice from gear manufacturer).

    Reminds me of a few occurrences on F27 Dowty NLG where a similar thing happens on the wheel lever shock absorber mounting lugs, see here for a report on one such instance
    http://rnsa.is/media/1433/2008-05-21_m07407_aig35_tf-syn_final_report.pdf

    With the F27 there was a mandatory modification to carry out a heat treatment to the main aluminium parts that basically changed the specification from DTD5024 to DTD5104 due to instances of stress corrosion (and also extended the safe life of a number of compoents); although the gear subject in the report should’ve been modified by that time it maybe other landing gears produced in that era by Dowty are susceptible to stress corrosion.

    As far as I’m aware the NLG on the F27 are still subject to regular NDT inspection on the shock absorber mounting lugs on the wheel lever amongst other parts.
