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.
