Just Winging It

I’ve nearly got the shop ready to start some real work on the airplane.  It’s been a lot of boring drudgery organizing shelves and setting up toolboxes, but in between I can always pause for a few minutes and look over the project.  Every time I look at that airplane I discover something new.  It’s so cool!

The one discovery I definitely wanted to tell you about is the story told by my wings.  I only have two right now, the port lower and starboard upper, the other two are safe in Abbotsford until the rest of the airplane is paid off.  These wings had been hung high up on the walls in Abby and I was never able to get a close look at them.  Once I got them to the hangar and put them on the wing rack, I immediately started looking for data plates.


As I’ve mentioned, just about every bit of the airplane has a modification plate on it from Victorian & Interstate Airways, where it was overhauled in 1943.  They stripped all of the fabric off and refurbished the entire airplane before putting it back into service.  The only part I had which didn’t have a V.I.A. plate on it was the port aileron.  It has a generic RAAF modification plate, and I know exactly why:  the port wings were badly damaged when A17-695 taxiied into my airplane in 1944, and the aileron had to be replaced with one that they had on hand at No. 1 E.F.T.S.  It was a spare, basically.

Because of that, I was anxious to find out if either of my wings were not original to the aircraft either, particularly the port lower.  Had the entire wing been replaced in 1944?

As always, history is complicated.


The port lower wing… is absolutely original.  The Victorian & Interstate Airways modification plate has a date of September 20, 1943, exactly matching the documented history of A17-370.  After the incident with A17-695, it must have been repaired or substantially rebuilt, but they kept the main spar where the plates are mounted.  Personally I can’t find any evidence of repairs, it looks like a factory-built wing to me, but perhaps I’ll uncover some as I disassemble it.


The starboard upper wing, on the other hand, is another story.  And that was a complete surprise!  It doesn’t have a V.I.A. modification plate, but rather, one that says “GAL.”  That totally threw me off… what on earth could GAL stand for?  And what could that have to do with A17-370?  Was this wing from a different Tiger Moth altogether?


The interesting thing, and the real clue, was the date on that plate.  June 5, 1943.  A17-370 went to V.I.A. in August, that doesn’t make any sense!  In June it was serving at 1 E.F.T.S., not being overhauled…  Another look at my transcript of its service records put an end to the mystery, and revealed just how complicated the history of a wartime aircraft can be.

Initially, when A17-370 reached 2,000 hours and required an overhaul, it was allotted to an outfit called Guinea Airways at the end of July, 1943.  A little over two weeks later, an entry says “Above allotment cancelled” and it is instead allotted to Victorian & Interstate.  I had interpreted that to mean it never made it to Guinea Airways, or perhaps it went there but they were too busy to look at it, so it went to V.I.A.  Now, I suspect that Guinea Airways (Ltd.) actually did begin to overhaul A17-370, but were stopped after only a couple of weeks for some reason.  In the rush to get 370 to V.I.A. to finish the overhaul, G.A.L. grabbed a spare starboard upper wing, probably one that had been completely overhauled, and installed it on 370.  I presume 370’s own wing would have taken too long to finish the overhaul, and when it was done it was probably installed on some other Tiger Moth.


So, someone out there has “my” wing.  And I have someone else’s.  It was war, and they did what they had to.  I’m dubious of anyone who claims an airplane that saw several years of service during wartime had a nice, simple history and is actually 100% original.  I’m actually relieved, the coincidence required for this to be any other airplane than A17-370 is beyond belief.  I’m as sure of its identity as a person can be, when no aircraft data plate is to be found.  And, so far, there’s been no sign that any of its parts were mixed up in India or even when it was in storage after the war (aside from the instrument panels).  Everything else on the airplane either came out of the factory on the airplane, or was swapped out during WWII.  Told you it was cool, eh?

Parts Manual into Excel

What seemed like a very long but necessary step is now complete, I’ve transcribed the dh.82a Schedule of Spare Parts (1943) from PDF into Excel.  This will allow me to better track the components of my Tiger Moth and also make it easier to search for missing parts by their various identification numbers.

I’m going to share this document here, eventually I will add a Downloads section for future versions of this file and more like it.

You may download v0.8 of the excel file here.

In future revisions I hope to cross-reference each part by drawing number, add the Canadian parts and part numbers, and generally continue to build it out to become more useful.  Eventually it will be ported over to a database where I will keep images of each part from my aircraft, reference images for manufacturing new parts, notes on the condition and origin of each part, etc.

If you have any resources that might be helpful in further expanding this document, please let me know.

Paperwork Progress

I’ve been busy on several projects lately.  First, transcribing the Schedule of Spare Parts into a digital format so that I can inventory, track and document each component of the Tiger Moth.  I am nearly finished with the first edition, and after that I will conduct a detailed inventory of what I’m missing from A17-370.  Afterward I plan to index the parts list for every known ID number of each part (Canadian, Swiss, Australian, etc) and also index it against the de Havilland drawings.  That will all be available for download here when it’s done.

Another digital project was the creation of a vector version of the de Havilland logo.  This may eventually be used to paint the wheels, but in the meantime will be incorporated into several graphical designs I’m working on.  If you’d like a vector copy of these logos for your own Tiger Moth project, let me know.

Finally, the historical research has continued and just last night I received high-resolution photos of the actual E88 card for A17-370.  This has allowed me to finish transcribing and translating the RAAF service history of the aircraft!  I’m still a bit puzzled about the 1944 event… further digging is required.  But this is GREAT information to have and these scans will play a big part in preserving the history of the aircraft.

With all that in mind, it was time to conduct a quick inventory of where I am and then figure out what I need to pursue next.
