33-83A ANE-111 Turbine Engine Vibration Test 09-29-2006
33-75A ANE-100 Guidance Material for 14 CFR § 33.75, Safety Analysis Describes guidance and acceptable methods, but not the only methods, for demonstrating compliance with the safety analysis requirements of Title 14 of the Code of Federal Regulations (14 CFR) § 33.75. 09-26-2007
33-11 ANE-111 Oxidation, Hot Corrosion, Thermal Fatigue, and Erosion Characteristics Testing to Support 14 CFR, Part 33, § 33.15, Compliancefor Turbine Engines

This advisory circular (AC) describes an acceptable method, but not the only method, to support certain comparative assessment compliance findings to Title 14 of the Code of Federal Regulations (14 CFR) part 33, § 33.15, Materials, for turbine engine projects. Comparative assessment of certain data is often necessary to show the required functional and durability equivalencies between engine combustor and turbine section parts from different design or manufacturing processes, e.g., parts manufacturer approvals (PMA) versus type design parts. These equivalencies relate to oxidation, hot corrosion, and thermal fatigue and erosion characteristics in the engine environment. This data is necessary to support overall FAA design approval of turbine engine and auxiliary power unit (APU) parts approved under PMA, type certificate (TC) design change, supplemental type certificate (STC), or repair or alteration authority.

33-10 ANE-111 Statistical Analysis Considerations for Comparative Test and Analysis Based Compliance Findings for Turbine Engine and Auxiliary Power Unit Replacement, Redesign and Repaired Parts

a.   This advisory circular (AC) describes acceptable statistical methods, but not the only methods, to help develop substantiating data for comparative test and analysis compliance findings. The findings support the Federal Aviation Administration (FAA) approval of turbine engine and auxiliary power unit (APU) replacement, redesign and repaired parts produced under:

(1)  Parts manufacturer approval (PMA),

(2)  Type Certificate (TC),

(3)  Supplemental Type Certificate (STC), or

(4)  Repair or alteration.

b.   The AC describes statistical principles that can be used to help determine adequate sample sizes for a comparative showing of equivalency of parts from different design or manufacturing processes. The guidance in this AC is acceptable for determining sample sizes and/or populations of specimens. The resulting data may be used to support a showing of compliance to the airworthiness requirements of Title 14 of the Code of Federal Regulations (14 CFR) 21.303, 14 CFR part 33, 14 CFR part 43 and Technical Standard Order (TSO) C77.

33-9 ANE-111 Developing Data for Major Repairs of Turbine Engine Parts

 

a.     This advisory circular (AC) provides information and guidance on developing the technical data needed for major repairs of critical and complex turbine engine parts.  This guidance will help persons developing major repair data meet the requirements of Title 14 of the Code of Federal Regulations (14 CFR) part 43 to restore the engine to at least equal to its original or properly altered condition.  This does not mean that a repaired part must be returned to a factory-new condition.  However, the engine on which the repaired part is installed must remain airworthy and in compliance with the applicable regulations.  For repairs of turbine engines and parts, the applicable requirements are Airworthiness Standards: Aircraft Engines (14 CFR part 33) and Fuel Venting and Exhaust Emissions Requirements for Turbine Engine Powered Airplanes (14 CFR part 34).
 
       b.    Additionally, this AC provides guidance to assist persons developing major repairs with developing a continued operational safety plan.  It also helps them evaluate engine parts recovered from accidents and incidents prior to making a repair.

33-8 ANE-111 Guidance for Parts Manufacturer Approval of Turbine Engine and Auxiliary Power Unit Parts under Test and Computation

This advisory circular (AC) provides guidance for developing substantiation data to support the design approval of critical and complex turbine engine and auxiliary power unit (APU) parts produced under parts manufacturer approval (PMA). This guidance is for the comparative test and analysis method used to show compliance to the airworthiness requirements under test and computation, per § 21.303 of Title 14 of the Code of Federal Regulations(14 CFR). This method supports showing the engine or APU still complies with 14 CFR part 33 and Technical Standard Order (TSO) C77.

b. Additionally, this AC provides information on developing a continued operational safety (COS) plan and part numbering for turbine engine parts.

33-7A ANE-111 Guidance for 30-Second and 2-Minute One-Engine-Inoperative (OEI) Ratings for Rotorcraft Turbine Engines This advisory circular (AC) provides guidance and acceptable means, but not the only means, for demonstrating compliance with the specific requirements applicable to 30-second and 2-minute One-Engine-Inoperative (OEI) rotorcraft turbine engine ratings in part 33 of Title 14 of the Code of Federal Regulations (14 CFR part 33). 06-11-2009
33-6 ANE-110 Weld Repair of Aluminum Crankcases and Cylinders of Piston Engines Provides information and guidance concerning acceptable means, but not the only means, for the development of process specifications for weld repairs on crankcases and cylinders of piston engines. 12-20-1994
33-5 ANE-110 Turbine Engine Rotor Blade Containment/Durability Provides guidance and acceptable methods, but not the only methods, that may be used by an applicant in showing compliance with the turbine engine rotor blade containment requirements of Part 33 of the Federal Aviation Regulations (FAR). 06-18-1990
33-4 ANE-110 Design Considerations Concerning the Use of Titanium in Aircraft Turbine Engines Provides guidance and acceptable means, not the sole means, by which compliance may be shown with the design requirements of Part 33 to minimize the probability of the occurrence of an internal fire when titanium is used in aircraft turbine engines. 07-28-1983
33-3 ANE-100 Turbine and Compressor Rotors Type Certification Substantiation Procedures Sets forth guidance and acceptable means, not the sole means, by which compliance may be shown with the turbine and compressor rotor substantiation requirements in FAR Part 33. 09-09-1968
33-2C ANE-111 General Type Certification Guidelines for Turbine Engines

This advisory circular (AC) provides general guidance concerning type certification projects for aircraft turbine engines. This AC applies to certain sections of Title 14 of the Code of Federal Regulations (14 CFR) parts 21, 33, and 45, and describes or references methods of compliance that may be acceptable for engine type certification work. This guidance is general in nature, and where necessary, further reference is made to other documents, which may be the primary source for information on a particular subject.
