Aircraft Service Center Processes
Presentation 12
2
What can a Service Center do for you?

• Develop STC for non-group aircraft
• Covered in another presentation
• Apply SL/SB/STC on group aircraft
• We will discuss here
• Assist in obtaining operational approval
• Additional services ranging from one stop shop
  to a handshake

3
What is a group?

• Group aircraft that are of nominally
  identical design and build with respect to all
  details that could influence the accuracy of
  height keeping performance

4
How do you verify your aircraft qualifies as a
group participant?

• Evaluate any existing modifications
• Assure static system conforms
• Assure avionics meet group standards
• Assure systems are operating within tolerances
  (autopilot performance)

5
What are your first steps?

• Evaluate Engineering Solutions, more than one
  method of compliance may be available
• Locate capable and qualified Service Center
• Obtain data package
• STC Certificate(s) or SB, Letter of entitlement,
  Flight Manual Revision or Supplements,
  Maintenance Manual Revision, Operational Test
  Procedures, etc.

6
Once you have selected a method of compliance and
a service center, what must you do?

• Prior to Maintenance
• Verify AFCS stability performance
• Confirm required parts and equipment are present

7
What will the service center do?

• Perform incoming inspections, avionics functional
  checks, pitot static leak checks
• Service center will apply modification
• Equipment Changes
• Skin work
• Pitot Static System Changes
• Paintwork
• Service center will test and inspect, recommend
  aircraft for return to service

8
What is next?

• At conclusion of service center work you will
  have an, RVSM Compliant Airframe
• Next after ensuring compliance FAA Aviation
  Safety Inspector (ASI) makes PTRS entry
• ASI will evaluate operator program and
  procedures, maintenance program, MEL
• Upon issuance of LOA or OpSpec you will have
  airframe and operator authorization

9
What can go wrong?

• Problems found with in-service aircraft
• Paint
• Stripes in the critical area
• Chips
• Bubbles
• Cracks
• Bumps
• Fisheyes

10
More that might go wrong

• Problems found with in-service aircraft
• Pitot Static
• Leaky systems
• Inoperative Pitot Static heat
• Autopilot
• Cable Tensions
• Servo Capstan problems

11
Still more that might go wrong

• Problems found with in-service aircraft
• Fuselage
• Excessive Skin Deviations (waviness)
• High Spots at Frames
• Uneven Skin Seams
• Skin Repair in critical areas
• Access or Inspection panels out of tolerance
• Latches or Hinges out of tolerance
