Aircraft part number list v6
________________________________________
It's been a while since this list was updated so here you go - I have added a load of new Air Ministry prefixes. There seems to be some contention around the de Havilland part number section. If any DH expert wants to re-write please do.

Just a note - if you are going to copy and paste the list and use it on your own website or any other form of publication please credit the forum. Posting a link would be great.

Anyone know which aircraft 26KF is?

Notes on De Havilland part numbers (posted by AgCat):

It was not the norm for de Havilland to prefix part numbers with the letters DH. In the early years of Stag Lane design all drawings were numbered in a single numerical sequence. This covered types such as the DH 60 series, through to the Tiger Moth (DH 82) and Fox Moth (DH 83) etc. From memory, I think it was perhaps the Dragon (DH 84) which introduced a model designator in the drawing number but I would have to check if that is correct. Thus, the first element of the drawing (or part) number denoted the model, followed either by the drawing number or (for later types) a system designator and then a drawing number.

Thus, the configuration of de Havilland part numbers for the Chipmunk is C1-TP-313. This number denotes a Chipmunk part (C1) for the tailplane (TP). Other systems were denoted by letters such as CF (Controls, flap) and FS (fuselage, structure). Part numbers for the Dove and Devon start 104, the Heron 114, the Trident 121 etc. Strangely, de Havilland used to 'pick and mix' its parts and bits with Dove part numbers are still used on the Nimrod MRA4!

The early single numerical sequence of de Havilland drawings covered all types from the DH 60 to the DH 89 EXCEPT the DH 87.

For the DH 87 each part was designated by a three-digit prefix comprising a single digit followed by the Type number. The first digit was used to denote the location with the aircraft the part could be found. This system gave a much wider range of possible part numbers as the complexity of aircraft increased. The designation system for the DH 87 Hornet Moth followed this sequence:

187*** Fuselage
287*** Planes
387*** Electrics
487*** Empennage
587*** Undercarriage
687*** Engine installation
787*** Flying controls
887*** Instruments
987*** Miscellaneous

At a late stage of Dragon Rapide/Dominie development the drawing sequence 989*** was introduced for parts used mainly in the various radio fits applied to the aircraft.

For the DH 90 to 93 inclusive, the same numerical designation system as for the DH 87 was used; ie;

190*** + 191*** + 192*** + 193*** - fuselage parts for the respective type. In some cases a 'zero' designator was used (ie 091***) for general arrangement drawings etc.

With the DH 94 the same system of designating part numbers by the aircraft type and its location on the aircraft was used but instead of using a single digit prefix to the type number, a letter suffix was used. For example:

94A*** General
94C*** Controls
94E*** Engine installation
94******* Fuselage
94N*** Instruents/electrics
94P*** Petrol and oil
94T*** Tailplane
94U*** Undercarriage
94W*** Wings

This system then continued on subsequent aircraft types, with the letters after the type number being used more widely to discriminate between aircraft system; eg, on the Chipmunk:

C1-C******* Controls, flaps
C1-FS*** Fuselage, structure

As well as the type-specific drawing series, de Havilland used other generic designations:

DHA and DHS - used to denote de Havilland standard parts or processes applicable to more than one aircraft type.
J - used for standard material sections used across all types.
R - used for Repair drawings. For the early types using the original all-numeric drawing series the repair drawings were mixed up in a single R-series. Later models included R as a prefix to a number allocated in the normal drawing sequence; eg, from the Chipmunk RC1-FS*** would be a repair drawing for damage to the fuselage structure. As a slight complication, some repair drawings were prefixed RD - repair drawing - rather than R, as if the system was not complex enough already.

AN ADDENDUM BY BRUCE:
The DH thing is slightly out - on Mossie, the Letter is a prefix - ie L98 is a part of the engine system. Vampire is (eg) A00, but after Vampire it changes to the system shown for the Chipmunk.

Venom and subsequent Vampires can be a mix of the two.

Notes on the CAC Wirraway, Wackett, Boomerang series of aircraft (Posted by Mark Pilkington):

The Wirraway has a number of models built from CA-1 through to CA-16 and carries part numbers originating from the NA-16 as well, resulting in part numbers of:

19- (NA-16)
01- CA-1 Wirraway mark 1
03- CA-3 " "
05- CA-5 " "
07- CA-7 Wirraway mark 11
08- CA-8 " "
09- CA-9 " "
16- CA-16 Wirraway mark 111

10- CA-10 Divebomber wings and centre-sections (fitted retrospectively to existing aircraft and in production to CA-16 aircraft)

All subsequent Wirraways carry a mixture of parts inherited from the earlier models where parts have been upgraded or added, ie a CA-16 may still carry many CA-1 parts etc if they have not subsequently been upgraded in design.

The 02- part numbers do not relate Wirraways at all as the CA-2 is the Wackett Trainer prototypes.

The 03- part numbers do not relate to Wacketts at all as the CA-3 is a Wirraway model, and the production Wacketts are the CA-6.

02- Wackett Trainer Prototype
06- Wackett Trainer production trainer (which carry the odd 02- part)

12- and 13- are Boomerang parts relating to the CA-12 and CA-13 Boomerang, as well as the CA-19 Boomerang, the latter two types had many CA-12 parts as the 13- and 19- part numbers only related to those parts that changed between the models.

12- CA-12 Boomerang production fighter
13- CA-13 Boomerang production fighter
14- CA-14 and CA-14A Boomerang turbocharged Prototype
19- CA-19 Boomerang production fighter

Note that the 19- Boomerang parts are drawn as CAC drawings and are not with 19- parts in the early Wirraways based on NA drawings from NA-16, the parts do not identify themselves as CAC or NA, however the historical drawing sets previously held by CAC/HdeHV clearly contained North American drawings for the Wirraways 19- parts ,and these are identical to the equivalent parts in many of the later NA products including the T-6 and SNJ deriviatives, despite carrying later 88- etc numbers in the NA number blocks.

obviously other CAC parts numbers are:

04- CA-4 Woomera prototype
11- CA-11 Wommera production Bomber
15- CA-15 "Kangaroo"? prototype
22- CA-22 Winjeel Prototype
25- CA-25 Winjeel Production Trainer
26- CA-26 Avon Sabre Prototype
27- CA-27 Avon Sabre production fighter
28- CA-28 Ceres Cropduster

This CAC model number information is all largely available in books such as the Stewart Wilson series on the CAC aircraft in RAAF service and there is a strong correlation between aircraft model and part number prefix.

CAC largely duplicated the North American numbering system with the initial number 01-, 16- indicating the model of aircraft (or more correctly production run block) while the next numbers formed a group of parts all related to the same elements of structure:

ie

xx-10xxx in General Assembly drawings
xx-13xxx is wing Centre Section
xx-14xxx is wing outer panel
xx-21xxx is horizontal stabiliser
xx-22xxx is elevator
xx-23xxx is fin (vertical stabiliser)
xx-24xxx is rudder
xx-33xxx landing gear
xx-40xxx power plant
xx-51xxx Instrumentation

This is consistant across Wirraway, Boomerang and Wackett drawing indexes that I hold and referenced for this post

It is also consistant within the North American T6G drawing index that I also hold, which is full of earlier T6 production run parts such as:

36-
49-
52-
55-
66-
77-
88-
121-
168-
182-

as well as very early parts inherited from the NA-16 design including
19-
23-
25-

which are all North American drawing parts which should not be confused with the similar CAC numbered parts above for Boomerangs or Winjeels but in the 19- series may be the identical part and drawing to that carried in the Wirraway.

Notes on the T6 series of aircraft (posted by Mark Pilkington):

In regard to North American products the type/drawing/part numbers and aircraft type production numbers for the T6 family are:

16- NA-16 series
19- BT-9
28- NJ-1
36- BC-1
49- Harvard I
54- BC-2
55- BC-1A
58- BT-14
59- AT-6
64- NA-64
65- SNJ-2
66- Harvard II
68- NA-50A (P64)
74- Harvard II
76- Harvard II
85- SNJ-3
88 - T6C, T6D, SNJ-4 SNJ-5
119- T6D
121- T6D, T6F
168 - T6G
182- T6G
186- T6J

As with the CAC Wirraway the "T6" derivitives all subsequent models may carry a mixture of parts inherited from the earlier models if they have not subsequently been upgraded in design.
