Clipper Golden Eagle: Engine No 1 Instruments

Hi all,

Dan Vincent and I recently visited the New England Air Museum in CT. They have the preserved cockpit (just the cockpit!) of Pan Am's N714PA (Clipper Golden Eagle).

Note that the instruments for engine number 1 are different to the rest (and there's a clear separator between them and the rest). Does anyone know why? Was it maybe used an an engine test bed? Just curious...

Thanks!

Tony

I think it's absolutely hilarious that, other than having 4 thrust levers instead of two, the control stand is an absolute dead wringer for the 737, right down to the parking brake handle.

If it's not broken, don't break it!  Wink

This was the first 707-320, so it might well be due to flight testing. But then why was the aircraft not returned to production specification?

That's somewhat weird. I can't find any mention of use as a test aircraft after Aeroamerica stopped using it. Just a couple of leases to PIA and some charter stuff. And then it was scrapped. Most likely some of the instruments got removed as salvageable parts, and they just stuck something that fit into the cutouts at the museum.

Was it #1 that didn't have the turbocompressor? IIRC, on 707's, only three of the engines had a turbocompressor (for cabin pressurization...). Still, I don't think that would explain the different instruments on #1.

From what I can tell, this is definitely an early build 707 (1 piece Capt.&F/O instrument panels - Not 3 Piece) and the rectangular autopilot surface position indicator and RMI/Compass switching panel are a dead PAA giveaway.

Compare with other -321's:

Yep, here's the history of the plane:

I thought that too. But if you look closely, there's a clear separator between the engine 1 instruments and the rest. Maybe I'm reading too much into this!!!

Anyway, thanks for the replies, guys.

It seems to have had one fitted, see this pic, you might have to zoom in on the number 1 engine.

The aircraft was used for a short time (leased) by Pratt&Whitney for test flying new engine types...note the additional engine instruments in the rectangular box nearby.
