CAF PBY CAF Lake Superior Squadron's PBY Catalina Restoration Update

The PBY Catalina played a crucial role in World War II, both in long-range reconnaissance and U-boat suppression, not to mention air sea rescue missions and other vital activities. The CAF Lake Superior Squadron, based in Duluth, Minnesota, is currently hard at work restoring a PBY back to flying condition.

In May 1998, PBY-6A Bu.64097 was flipped on her back during a heavy storm. Her replacement, Bu.64092, flew for a few years while still in its firebomber configuration, but significant fuselage corrosion eventually grounded her as well.

The squadron is doing something radical, and probably never before attempted outside of the military. They are rebuilding the damaged, but relatively corrosion-free fuselage of Bu.64097 and replacing the crumpled wing with that from their other former fire bomber, Bu.64092. It is a massive undertaking, but the team has made remarkable progress since the project began in 2009. They have already grafted the two aircraft together and are well on the way to forming one airworthy airframe. Since the fuselage came from Bu.64097, that will be the identity of the aircraft once the restoration is complete.

The above three images show the left wing trailing edge where the aileron attaches. This section is now in the process of being recovered. The right side is currently being soda blasted. Then comes an inspection checking for damage that needs to be repaired or replaced. Then the area will be painted zinc chromate for corrosion prevention. Then comes the fabric covering.

The nose/bow section during the restoration. This area had a clipper bow during its firebomber days, but as can be seen in the story’s leading photograph, a nose turret is now installed.

The above picture shows one of the center section trailing edges. After the outer sections are finished the large inner sections will undergo the same treatment the outer sections had. Altogether there are four of these large parts, but it will be easier to work on them than the outside parts due to their large flat surfaces as compared to the multiple curves and aileron attachment points to work around on the outer panels.

The above two images show the trailing edge being test-fitted to the wing. The team is checking to make sure everything still fits properly before covering the section with fabric.

The above two images show the tail section minus the control surfaces. This area was completely destroyed by the wind storm at Fleming Field in St Paul MN. The fabric covered controls are finished and are now stored awaiting their mounting as one of the last parts of the restoration.

The above two images show the interior of the aircraft. There isn’t a lot to see here just yet as most of the insides were been removed for restoration, including the floorboards. There is a strong chance that this area will be painted this  summer.

The above two images show the R-1830 engines. Rebuilding these will be the last effort in the restoration, although the Squadron does periodically manually turn the engines through to keep them lubricated. They will probably undergo their restoration sometime this summer
