CHAPTER 46 EVALUATE 14 CFR PART
OR MORE LEASED MAINTENANCE PROGRAM AUTHORIZATION: U.S.-REGISTERED AIRCRAFT
Section 1 Safety Assurance System: Authorize an Operator (Lessee) to Maintain a Leased Aircraft
3-3941 REPORTING SYSTEM(S). Use Safety Assurance System (SAS) automation and the associated Data Collection Tools (DCT).
3-3942 OBJECTIVE. This chapter provides guidance for authorizing an operator (lessee) to maintain a leased aircraft in accordance with the previous
operator’s (lessor’s) current and approved maintenance program for that type of aircraft.
A. Leased Aircraft. Title 14 of the Code of Federal Regulations (14 CFR) parts
§ 135.411(a)(2) operators
have leased aircraft from other air carriers, with the understanding that the aircraft will be returned to the previous operator upon termination of the lease. It may be to the lessor’s
advantage to have the aircraft maintained under the lessor’s maintenance program rather than the lessee’s program so that it can be readily integrated back into the fleet when
the lease expires.
B. Lessee’s Responsibilities. The key factors in this type of arrangement are the lessee’s capability of accomplishing the program to the
lessor’s standards and the lessee’s responsibility for the effectiveness of the adopted maintenance program.
3-3944 ACCOMPLISHING THE TASK. An operator intending to maintain a leased aircraft in accordance with the lessor’s program must substantiate that:
· The lessor’s program, as carried out by the lessee, will result in a level of
airworthiness equivalent to that of the aircraft maintained by the lessee.
· The lessee is capable of accomplishing the lessor’s program with regard to facilities,
equipment, personnel, training, etc.
· The lessee arranges for the maintenance of equipment or installations not covered by
lessor’s program, such as life vests, life rafts, emergency locators, pressure cylinders, etc.
· The lessee takes adequate steps to ensure that maintenance programs for the leased aircraft
and any owned aircraft are kept separate and are applied to their respective aircraft.
· The lessee receives and maintains the records required by part
121.380 or §
has arranged with the lessor to gain access to these records. The lessee must have and maintain adequate records to determine the status of applicable Airworthiness Directives (AD),
life-limited parts, time‑controlled items, and inspections.
· The lessee has the necessary records to schedule maintenance tasks at the intervals specified
by the lessor’s program or has arranged with the lessor for this service.
· The lessee has adequate manuals and technical material to accomplish the lessor’s
· The lessee amends its Weight and Balance (W&B) program, as necessary, to accommodate the
leased aircraft. This may require coordination with the principal operations inspector (POI).
· The lessee has procedures for reporting maintenance activities and data to the lessor (e.g.,
component replacements, scheduled inspections, AD notes, engine trend monitoring data, and major repairs).
3-3945 APPROVAL. Adopted maintenance programs for aircraft on lease shall be approved by operations specifications (OpSpecs) (paragraph D080). Provisions
for additional maintenance requirements and maintenance of equipment that is not included in the lessor’s program shall be listed in a nonstandard paragraph in those OpSpecs.
3-3946 COORDINATION REQUIREMENTS. This task requires coordination with the principal maintenance inspector (PMI), principal avionics inspector (PAI), and
the POI. This task may also require contact with the lessor’s certificate-holding district office (CHDO) and/or the Aircraft Evaluation Group (AEG).

A. Schedule and Conduct an Informal Meeting. The operator/applicant must indicate its intention to utilize aircraft under a short-term lease arrangement
with the use of the lessor’s maintenance program. Advise the operator/applicant of the following requirements:
1) The aircraft must conform with all applicable requirements of parts
2) The lessee must have the capability to support and maintain aircraft in accordance with the lessor’s program to include:
· Equipment, and
3) The lessee must have current records to determine the status of the following:
· Scheduled inspections,
· Life-limited items, and
· Time controlled components.
4) The lessee must have the current W&B data for the leased aircraft.
5) The lessee must provide a copy of the contract between the lessor and lessee to the CHDO.
6) Lessee must initiate procedures for transfer of aircraft maintenance and performance data to lessor.
7) Lessee must have procedures that ensure that maintenance programs for the leased aircraft and the lessee’s own are kept separate and are applied
to the respective aircraft.
B. Conduct Formal Meeting. The operator should state that aircraft, records, and facilities are ready for inspection and must present required data
and proposed OpSpecs.
C. Review the Contract. Examine the following:
· Length of contract,
· Maintenance responsibilities, and
· Data reporting requirements.
D. Review Lessor. Review lessor’s maintenance program and OpSpecs.
E. Review Lessee. Review lessee’s technical data. Ensure that lessee has all appropriate technical data to support the aircraft (see Volume 3,
Chapter 43). This includes such items as maintenance manuals, wiring manuals, etc.
F. Ensure Lessee. Ensure that lessee has adequate personnel to support the aircraft (see Volume 3, Chapter 31).
G. Differences in Equipment. Determine if differences in equipment and installations have been addressed and personnel have been trained accordingly.
H. Facilities are Sufficient. Ensure that facilities are sufficient to support additional aircraft. This includes special tooling, test equipment,
spare parts, and equipment.
I. Determine Adequate Procedures. Determine if adequate procedures are in place to ensure the separation of maintenance programs for leased aircraft.
Ensure that these procedures are applied to the respective aircraft.
J. Review W&B Data for Leased Aircraft. Ensure that data is compatible with lessee’s program. If data is not compatible, ensure that
procedures have been developed and are in place.
K. Review Aircraft Records. See Volume 3, Chapter 31.
L. Inspect Aircraft, if Necessary. See Volume 6, Chapter 2.
M. Review OpSpecs Parts D and E. See Volume 3, Chapter 18.
N. Analyze Results. Determine whether the operator/applicant meets all necessary requirements.
O. Meet with Operator/Applicant to Discuss Deficiencies. Advise the operator/applicant on which areas require corrective action.
