(2) The first step consists of providing all preliminary data, laboratory testing, and evaluation; the L-38 engine test; and the 150-hour engine endurance test of an LE TIO-540 engine. The applicant must perform these tests in accordance with SAE J1899.
(3) The compliance plan must reference the applicable J1899 sections. The following table summarizes the relationship between J1899 and part 33; applicants can use it to aid in developing their compliance plan.

3.8.2, B7
(4) For engines certified under CAR 13, applicants must reference the equivalent requirement from that regulation.
(5) Some differences exist between § 33.49 and the J1899 endurance test of section B6.5.
For example, J1899, B6.5, does not require that the engine be operated at critical and 8000 ft.
altitudes, as required by § 33.49(e)(1)(ii), and does not require that accessories be loaded, as required by § 33.49(a). In addition, the turbo supercharger 50-hour test specified in § 33.49(e)(1)(iii) is not included in the J1899 test. While the applicant must demonstrate compliance with each applicable FAA regulation, the J1899, B6.5, test is acceptable to show that the engine oil or additive is acceptable for the limited flight test to be performed in Step 2 below.
Appendix 1 A1-3
(6) The 150-hour endurance test specified in J1899, B6.5, is considered an official FAA test and, therefore, subject to FAA certification test requirements. These include conformity of the test lubricant or additive, conformity of the test hardware and apparatus, and FAA testing oversight. Applicants must submit a test plan for approval, and the responsible FAA aircraft certification office (ACO) must issue a Test Inspection Authorization, prior to conducting the tests.
(7) Upon completion of the above requirements, the FAA will issue an STC to authorize flight testing of the specified LE and TCM engine models in accordance with appendix C of SAE J1899.
b. Step 2: Flight Testing.
(1) Flight evaluation is the second step, using the specified LE and CMI engine models, as described in SAE J1899, appendix C. In this step, the applicant must conduct a long-duration flight test of 500 hours on the specified LE and CMI engine(s).
(2) The FAA has delegated oversight of these tests to the engine manufacturers under their design approval holder (DAH) authority. Test conformity and procedure requirements need only meet the engine manufacturer’s requirements for a design change. Although the company designated engineering representative is responsible for FAA oversight, the FAA retains the authority to observe the testing or review the engine manufacturer’s approval of the product, if necessary. The applicant must ensure that the engine manufacturer is participating in the evaluation of the oil and has access to sufficient data to assess the acceptability of the product.
(3) Step 2 allows the SAE technical team to complete the evaluation of the oil. Once completed, the team will determine if the oil must be added to the U.S. Navy’s Qualified Products List (QPL). Engine manufacturer approval of the product is accomplished by reference to the QPL in LE and TCM service documents.
