AS9100D
A detailed look at the process of how our team repairs the F5 Canopy.
F-5 Canopies with excessive damage can be repaired, restored, refurbished.
COC Qualified “Work Instruction” are in compliance with AS9100 Rev. D and Technical Orders (T.O.’s)
We provide complete Certificates of Conformance (C of C’s) for every canopy we repair.
COC’s AS9100D Scope
“Supporting of Aging Military Aircraft through Repairs, Refurbishment and Spare Parts.”
Step 1: 3D Scan
COC techs 3D Scan the damaged canopy. For smaller aircraft assemblies, we use a hand-held photogrammetry scanner.
Step 2A: Plastic Media Blast to Aerospace Approved MIL-P-85891A
Step 2B: Media Blasting
Media blasting renders the canopy free of any paint, sealant and primers enabling COC technicians to perform first initial visual inspection.
Step 3: Identify major areas of damage and corrosion
Establish the Repair Plan – what parts need to be repaired, replaced.
Step 4: 3D Scan
Canopy undergoes penetrant inspections and Eddy Current fastener inspections.
Step 5A: Pre-Measurement
Using the F-5 Basic Dimensions, COC incorporates the Fuselage Station (FS) measurements where the canopy fits to the airframe.
Step 5B: Photogrammetry CAD Model
Scan of damaged canopy is converted to CAD Models.
Using the Photogrammetry equipment, we have both the exact dimensions and a photographic representation.
Step 6A: Canopy CAD Model into Fuselage CAD
We take the CAD model of the damaged canopy and ‘insert’ it into fuselage Basic Dimension Data CAD model. Now we can measure what we need to fix.
Step 6B: Overlay the Basic Dimension Data for fuselage and canopy.
Comparing with ‘Scanned’ damaged canopy to determine what to repair.
Step 6C: Compare Dimensions to Data
Compare damaged canopy dimensions to the Nominal Data for the reassembly process.
Step 7A: Design & Repair Canopy Security Fixture
Design Fixture to secure canopy while repairing it using original engineering dimensions and measurements.
Step 7B: Design & Repair Canopy Security Fixture
The Fixture to secure canopy is a very simple design We do not need a ‘traditional’ type fixture because we have all the dimensions in our CAD files.
Step 8: Determine all the key measurements for the important dimensions.
- Circumference of canopy hoops, FWD & AFT
- Centerline of canopy lockdowns 4 places, 2 RH & 2 LH – lockdown roller pins
- Length and width, FWD hoop to aft hoop (beams)
- Height from canopy base to top of hoops
- Do not measure canopy glass (panel) surface as this will be replaced with new glass
- Rear canopy assembly aft of rear hoop; aft canopy glass.
- Sheetmetal fabrication, include rivet locations, with attach brackets.
- Locations of brackets/supports, alignment of brackets/supports for reinstallation, to ensure alignment with fuselage mating supports.
- Rear skin at join line; rear fuselage with rivet locations (FS264.104 - FS 270.477)
Step 9: Anodize and Prime Parts
The parts that pass inspections are reprocessed with new anodize and prime and ready to be reassembled.
Step 10: Canopy Reassembly
Canopy is reassembled with all new fasteners. Technicians check dimensions with the 3D Scanners to maintain alignment.
Step 11: Final Finishes
Canopy is complete, upgraded from -513 to -515. Apply final paint, crate and ship back to customer.

COC’s Canopy Refurbishment & Restoration
Significant savings over cost of newly manufactured canopy
Return to Flight is four (4) times faster
For F-5 aircraft, new replacement canopies are extremely expensive and time consuming to attempt manufacture.
