American
Aero Services, owned
by Gary and Carole Norville, is located in New Smyrna Beach, Florida, 20
minutes south of Daytona Beach. Since its inception in 1981 the facility
has restored and maintained various types of warbirds. Many of American
Aero’s restorations have become award winners at air shows including
Oskosh and Sun-n-Fun.
Since
November 1991 American Aero has maintained Boeing B-17G Nine-o-Nine. The B-17 comes in each year for its annual inspection
and year-end maintenance, which is conducted over a period of two to three
months commencing in November. While down for its annual inspection the
aircraft has everything from minor repairs and engine changes to sheet
metal and systems overhauled.
In
July 1994 the B-17 came in before its scheduled winter maintenance due to
a problem with contaminated fuel purchased in California. Fearing an
emergency airworthiness directive from the F.A.A. against the aircraft
engines that obtained this fuel, the bomber returned to Florida early from
its national tour.
All
engines, fuel and oil tanks, accessories and hoses were removed and
overhauled at the request of the petroleum company.
During
this project it was decided that American Aero should pull the wings from
the fuselage and inspect the spar terminal ends for cracks and corrosion.
Gary
Norville takes up the story “We used a crane to lift the B-17 and then
retracted the main gear, setting it down on 24 inch jacks and cradles.
Once this was accomplished we removed the outer wing panels and main wing
panels. All eight terminal ends were removed and inspected. The terminal
ends were then cleaned, NDT’d, nickel plated and baked to relieve
hydrogen cracks using visual and x-ray inspection. No damage was found in
the spar or terminal ends and they were re-assembled.”
The
wings were re-installed and once again the B-17 was back on its main gear.
In January 1995 the project was complete and Nine-o-Nine
was ready to commence its next nation-wide tour. An entire photograph
album was created to document what was found and repaired to maybe help
other B-17
Co-op members if they were faced with the same project.
March
1993 saw a new project aircraft delivered to American Aero Services for
restoration for The Collings
Foundation. One that would present many new challenges to the company
and one that would see them reach even higher standards of
attention to detail in their restoration work. Vought F4U-5NL
Corsair Bu 124692 was delivered basically as a rough fuselage on a center
section and gear, two outer wings, a vertical, horizontal, rudder, plus
several boxes of unoverhauled systems parts. So how did American
Aero Services tackle this one? Gary takes up the story again “We
started with a fuselage and cockpit restoration.
The cockpit sheet metal closeouts and shelves were fabricated and
installed. The entire hydraulics system was fabricated and replumbed by
Vince Santorelli. One of the big Challenges was that we only had a few
horizontal stabilizer ribs and old skins. The original dash 5 horizontals
were made with aluminum ribs and the surfaces were metallite (Parquet
balsa sandwiched between two thin pieces of aluminum). These were
undesirable due to unavailability of materials and ease of damage
following restoration. With help from Nelson Ezell we obtained F4U-4
horizontals blueprints and Jeff Mitchell fabricated and assembled new
ribs, spars and skins.”
Another
obstacle facing the team was a missing port oil cooler shoulder. “The
port and starboard were mirror image QEC’s for ease of change if
damaged. We disassembled the right hand shoulder and fabricated mirror
image parts to build up a left-hand shoulder assembly. Both outer wing
panels were reskinned from the ammunition bay doors to the wing butts and
installed, the right hand panel had the original radar pod installed”
adds Gary.
The
cockpit was laid out and restored, as it was originally when it served as
a night fighter with Navy Composite Squadron VC-3. So what detailing made
the Corsair so special? “The cockpit interior was flat black with all
the original type instruments overhauled. Our only modern instruments
consisted of a King HSI and VOR head that was located in the upper center
of the instrument panel. These could be hidden under a removable
radarscope head while on static display at airshows. The interior flash
hiders, gunsight and armament control panels were installed on top of the
glare shield. The modern avionics were installed in the right hand shelf
by Avionics Installations and could also be hidden with a plate carrying
original radio heads”.
Much
research was conducted so the plane was authentically restored and painted
in the markings it carried while flying 77 hours with VC-3 aboard the U.S.S.
Essex during the Korean War. At the business end an R-2800-26WD from Rudy
Blakey was installed and a custom induction system fabricated to
accommodate the down draft carburetor. A pre-oiling system was installed
along with a Halon fire
extinguisher system concentration on the power and accessory sections. All
the fuel, oil and hydraulic lines were fire shielded.
After
various ground checks leading up to numerous engine runs, and consequently
checking oil screens and sumps, Tom Crevasse flew the beautiful Corsair
for the first time in 1997.
Sadly,
during a photo flight on 4th April 1997 with Robert Collings
Jr. as pilot a miscalculation in fuel consumption lead to the Corsair
ditching in the ocean two miles South East of New Smyrna Beach – in 65
feet of water. Rob made an excellent ‘dead
stick’ landing which spared the
plane from a broken fuselage and allowed him abut 30 seconds to scramble
out of the plane before it sank. Very fortunately a fishing boat was
nearby to come to the rescue. After nine days underwater the Corsair was
raised to a barge and shipped back to dry land.
The
aircraft was towed back to the hangar and the team removed all the control
surfaces, wings, cowls and anything else that could be unscrewed or
unbolted and pressure washed everything. On completion all that remained
was the fuselage sitting on its center section and gear. All the cowling,
wings, control surfaces etc. were placed in pools behind the hangar for
soaking and daily water changes. The fuselage was pressure washed again
and covered in Corrosion X by Bootstrap Aircraft’s Craig McBurney.
Currently
the dash 5 is under rebuild again at American
Aero. How had the aircraft fared? Both outer wing panels suffered
severe damage along with the trailing edges of the center section. With
the flaps being lowered during ditching the hydraulic action of the water
tore them from the center section. The right hand outer wing panel
sustained heavy damage when the radome tore off, blowing out the last four
feet of spar. A new spar, ribs and skins were fabricated and at this point
both outer wing panels are 90% complete. Work is commencing on the
centersection wing butts and trailing edge structure, with flap gap doors
and drives being fabricated and installed. The saltwater had not adversely
affected the aluminum or steel with corrosion due to the prep and prime of
the metal from Chance Vought and
the first restoration, the magnesium parts however were a total loss. All
the magnesium parts have been replaced with other serviceable parts or
machined new ones from aluminum. The corsair should be back to its
original configuration in one to two years.
Currently
the shop maintains an array of other aircraft from undertaking structural
sheet metal repairs on Continental
Airlines DC-3A to performing winter annual maintenance on Jim Read’s
dash 5 Corsair. A recent project has been installing a leading edge gun
kit on his P-51D Mustang Excalibur.
The shop has six full time mechanics, three of them with Inspection
Authorizations undertaking current projects. Gary praises all the
mechanics in the shop, saying “If it wasn’t for them and the way they
work together none of this would be possible”. All facets of restoration
are done in-house, light and heavy sheet metal fabrication and repairs,
aircraft systems, welding, painting, research and assembly. Tom Walker is
currently fabricating and installing the systems on a hybrid AT-6 with a
Pratt & Whitney R-1830, while Steve Marquise is rebuilding flight
controls and flaps for a P-51C being assembled in the shop.
American
Aero have
a first class facility and an enthusiastic workforce with a proven track
record. We look forward to seeing many more award winning restorations
leave the shop. WW
