Another one of Lockheed's promo videos. In this one it shows how Lockheed performs a PDM (Programmed Depot Maintenance) of the Air Force's U2 Dragon Lady.
Interesting to watch some of the steps they have to go through (paint strip, checking over 40,000 rivets, almost complete dismantle) to make sure these airplanes stay flying in the environments that they do.





The U-2 Dragon Lady goes through Lockheed Martin Programmed Depot Maintenance (PDM) every 4,800 flight hours or every seven years. PDM involves the complete disassembly, inspection, repair and reassembly of the entire aircraft; ensuring its longevity and ability to fly at today's record-high operational rates. This thorough maintenance allows Lockheed Martin to collect data on airframe integrity, confirming that nearly 80 percent lifespan remains on the aircraft. The U-2 collects critical targets no other platform can, flying faster, deeper and with greater reliability compared to any high-altitude ISR aircraft since the SR-71

Yup, we have the same issues where I work. System operators hate it when I have to take a good operating machine down for a PM. Sometimes the systems don't like to be messed with.

You used to be able to make an entire Squadron of men cry by sending the message that an aircraft was due for PDM.

We used to get them back from the Depot and put them straight into a phase inspection to find all the things they screwed up.

Some years ago I watched a docu. that described the U2 as a F104 Starfighter with extra wide wings

It's actually worse. It's a lot more unforgiving than the -104 was.

I thought a Hammond organ was complex. Seeing something that size taken apart and reassembled gives me goosebumps. Knew a technician who used to go around repairing electronics. Kept a jar filled with the screws and bolts that he had left over after repairing each one ...
