Study Notes
Inspection Authorization & Maintenance Procedures
- Light piston twin engines under Part 135 require documenting any inoperative instruments as unairworthy, even if not listed in the MEL.
- For repairs using aluminum, the correct rivet specification is crucial. For 0.032 in. thick sheets, MS20455DD 5-5 rivets should be used.
- Inspectors cannot approve data for aircraft repairs or alterations; it's mandatory for the holding IA to use administrator-approved data for major alterations.
Inspection Standards & Documentation
- Type Certificate Data Sheets, such as No. E-273, contain critical engine data for Cessna 182L inspections.
- Repair station documentation must clarify the part's name for any major repairs.
- Inoperative equipment deferred under Part 91 must be inspected to ensure it doesn’t pose operational hazards.
Inspection & Airworthiness Directives
- Annual inspections can reveal nonessential items that are unairworthy, requiring entries in maintenance records.
- When inspecting composite materials, X-ray imaging is an approved method.
- Galvanic corrosion occurs between dissimilar metals, leading to potential safety hazards.
Propeller and Hydraulics Specifications
- McCauley propeller models indicate size through their designation; a hub and blade combination might result in effective diameters, like 80 inches for a specific model.
- The minimum bend radius for hydraulic hoses varies with operational pressure, with 90-degree bends requiring specific inch measurements; e.g., 3.38 inches for certain MIL hoses.
Engine Specifications & Maintenance
- Different aircraft types have distinct certification bases, with models like the Piper PA-28 falling under the CAR part 3 classification.
- Aircraft weighing calculations include unusable fuel and full operating fluids for accurate empty weight determination.
Regulation Compliance and Repair Standards
- The Federal Aviation Administration defines major alterations, such as those that change flight characteristics, and specifies documentation requirements for repairs.
- For major repairs, details must be maintained in technical files, including relevant design and specification data.
Certification and Inspection Requirements
- An annual inspection may be required for certain aircraft; the smallest required to carry a CVR is typically a multi-engine turbine or rotorcraft with specific seating configurations.
- Continued IA certification renewal requires fulfilling specific inspection criteria within timeline restraints.
Structural and Material Analysis
- In composite materials, warp direction is critical in strength, with warp at 0º to refer to the fabric roll.
- A 90-degree bend in metal sheets requires precise calculations regarding material allowance, with specific formulas for estimating bend allowances.
Airworthiness Reporting and Compliance
- The FAA mandates specific airworthiness entries, including revision dates for compliance.
- A delaminated composite structure must be repaired to prevent broken fibers, emphasizing the importance of timely repairs to maintain integrative strength.
Maintenance Recordkeeping & Repair Documentation
- Maintenance Release or Form 337 must describe the work for major repairs, ensuring proper communication of completed tasks.
- If the IA does not meet yearly renewal requirements, options include taking an oral exam for reinstatement.
Historical and Regulatory Context
- Older U.S. aircraft, specifically those over 30 years old, may have size adjustments for registration marks as allowed by legislation.
Conclusion
- Detailed adherence to documentation, inspection standards, and regulatory compliance is essential for safe aircraft operation and maintenance, upholding both safety and performance standards across various aircraft types and configurations.
