Section 6 Safety Assurance System: Conduct Spot Inspection of a Program Manager/Operatorís Aircraft
6-293 REPORTING SYSTEM(S).
A. Program Tracking and Reporting Subsystem (PTRS). For Aging Aircraft Inspections for Title 14 of the Code of Federal Regulations (14 CFR)
(part 91K) and
use the following activity codes:
∑ Spot Inspection: 3628, 5628.
∑ Structural Spot Inspection: 3647, 5647.
B. Safety Assurance System (SAS). For 14 CFR
(except Aging Aircraft Inspections)
use SAS automation to develop a Custom Data
Collection Tool (C DCT).
6-294 OBJECTIVE. This section provides guidance for observing and analyzing in‑progress maintenance operations for compliance with specific
methods, techniques, and practices in the program manager/operatorís inspection and maintenance programs.
A. Definition. A work package is the job task control units developed by the program manager/operator for performing maintenance/inspections. A typical
work package may include the following:
∑ Component change sheets;
∑ Inspection work cards;
∑ Nonroutine work cards;
∑ Appropriate sections of the maintenance procedures manual; and
∑ Engineering Change Orders (EO).
B. Federal Aviation Administration (FAA) Inspection Personnel. It is important that Airworthiness aviation safety inspectors (ASI) are familiar
with the type of aircraft to be inspected before performing the inspection. This can be accomplished through on‑the‑job training (OJT).
C. Coordination Requirements.
parts 121 and
follow SAS guidance for Modules 2 and 3 to request geographic inspector resources.
2) Airworthiness ASIs possess various degrees and types of expertise and experience. An ASI who needs additional information or guidance should
coordinate with personnel experienced in that particular specialty.
6-296 INITIATION AND PLANNING.
A. Initiation. Spot inspections can be scheduled as part of the work program, but may be initiated whenever a problem is noted, including
deficiencies noted during other types of inspections.
1) Spot Inspections Derived from the Planned Work Program or from SAS.
a) The number of spot inspections in the work program depends on the type and number of program manager/operator aircraft. After determining the type of
aircraft to be inspected, confirm the aircraft availability and scheduled maintenance functions with program manager/operator personnel.
b) If the maintenance to be observed is known, review the program manager/operatorís maintenance procedures manual to become more familiar with the maintenance
task. Review the following:
∑ Required Inspection Items (RII), if applicable;
∑ Forms used to document the maintenance task;
∑ Latest manual revision and date;
∑ Special tools and equipment used to perform the maintenance task; and
∑ Any other manual requirements relating to the maintenance task.
c) For geographic requests, in which the maintenance procedures manuals are not in the office, review the applicable sections of the program manager/operatorís
maintenance manual at the facility prior to performing this task.
d) Examining previous inspection findings provides the ASI with background information regarding problem areas found during other spot inspections. This
information can give an indication of how effective past corrective actions were in resolving previously identified problem areas.
e) The FAA provides information such as Airworthiness Directives (AD), Service Difficulty Report (SDR) summaries, maintenance bulletins, surveillance data, and
PTRS entries. This information should be reviewed, when available, to become familiar with current service difficulty information. While performing the spot inspection, ensure that
any conditions described in this information do not exist on the aircraft.
2) Spot Inspections Not Derived From the Planned Work Program. There are many situations while performing other surveillance activities that afford the
opportunity to perform spot inspections. For example, if a discrepancy is found during the inspection that requires maintenance, a spot inspection of that maintenance function could
6-297 MAINTENANCE RECORDS. During performance of the spot inspection, special attention should be paid to the following areas, as applicable:
∑ ADís current status, including the method of compliance;
∑ Overhaul records, including documentation containing the overhaul details and
∑ Major repair/alteration classifications and the use of approved data; and
∑ Replacement time of life‑limited parts.
6-298 PERFORMING THE SPOT INSPECTION.
A. Selecting a Maintenance Task.
1) Discuss with the maintenance supervisor what maintenance is currently being performed to determine what portions of that current
maintenance/inspection should be observed.
2) Special emphasis should be placed on observing maintenance tasks that involve RIIs. Problem areas to look at include the following:
∑ Persons performing inspections outside of their authorizations or limitations; and
∑ RIIs not being properly identified or accomplished.
B. Performance Standards.
1) Each program manager/operator has a maintenance/inspection program for their individual maintenance operations. For maintenance to be performed
on the program manager/operatorís aircraft, there must be corresponding provisions and procedures in the program manager/operatorís maintenance manual.
2) Each program manager/operator should have special procedures in the manual that ensure that persons outside of the organization perform maintenance
in accordance with the program manager/operatorís maintenance manual.
C. Discrepancies Noted During Surveillance. When deviations from accepted procedures are noted, it must be brought to the attention of maintenance
management that corrective action must be taken immediately. Discrepancies noted during the inspection may require followup at a later time.
6-299 STRUCTURAL SPOT INSPECTIONS.
A. Increased Surveillance. The Aging Airplane Safety Rule requires the FAA to validate the effectiveness of air carrier maintenance programs with regard
to structural fatigue and corrosion. In response, the FAA uses the structural spot inspection to perform surveillance of transport category aircraft undergoing ďC,Ē ďD,Ē or similar
ďheavy inspections.Ē Inspectors should coordinate and time their inspection activities with the certificate holder maintenance process.
Inspection Area. During the observance of a ďheavy inspection,Ē ASIs must pick an inspection area where maintenance has been started and where there could be possible
fatigue or corrosion problems (especially an area that is not usually open to inspection, such as under the galley or lavatories).
1) If inspecting an area where maintenance is in progress, the following should be evaluated:
a) While performing their job functions, are personnel accomplishing their job task per the work package?
b) Does the Aging Aircraft/Corrosion Control program provide the necessary guidance to evaluate and respond in a timely manner to structural fatigue
2) If inspecting an area where maintenance has already been accomplished, the following should be evaluated:
a) Are there any structural fatigue or corrosion problems evident?
b) If there are, were they identified by the person(s) responsible for that area?
If they were identified, was corrective action initiated and completed?
3) Is there an AD applicable to this problem? If there is an AD, what is the status of that AD?
NOTE: While inspecting these areas that are not normally accessible, look for evidence of structural major repairs. If a major repair was accomplished,
review the approved data for that repair.
6-300 PREREQUISITES AND COORDINATION REQUIREMENTS.
A. Prerequisites. Previous experience working with an operator/program manager with similar types of aircraft.
1) This task may require coordination between Avionics and Maintenance ASIs.
2) Geographic inspector(s) must coordinate with the certificate-holding district office (CHDO) to obtain knowledge of the operatorís maintenance
procedures and any other items of concern that may surface during routine inspections.
