This workgroup was tasked to develop a standardized oversight system for repair station and air carrier outsourcing surveillance. As such, the workgroup recommended a risk based oversight system that allows for continuous assessment of each repair station and prioritization among repair stations; targeting Flight Standards’ resources for use in the areas of highest risk. Additionally, certificate management can use a corresponding Risk Management Process (RMP) for issues of concern. This system is for use by Flight Standards personnel involved in the certificate management of 14 CFR part 145 Repair Stations including air carrier maintenance outsourcing.
Enhanced maintenance oversight will be accomplished utilizing the following components:
Risk Based Oversight System for Repair Stations (detailed in Section 2.1 below).
An enhanced baseline surveillance program for repair stations whereby the current PTRS 3650/5650 is divided into elements to better define the intent of the guidance and provide for more comprehensive surveillance.
A Repair Station Assessment Tool (RSAT) will provide an overall assessment of the repair station, identify potential risk areas, and update surveillance program.
A RMP will be initiated for issues of high concern.
An enhanced data recordation system to improve data reliability.
Enhanced tools for evaluation of air carrier maintenance outsourcing including an Outsource Oversight Prioritization Tool (OPT). (Detailed in Section 2.2 below.)
The section below discusses each of these topics in further detail.
This System Safety based approach identifies specific procedures that enhance the oversight of repair stations. The system is comprised of a baseline surveillance program, a repair station data package, a repair station assessment tool, and a risk management tool.
The overall oversight process involves the following steps:
A comprehensive Baseline Repair Station Surveillance Program.
A data package generated via Safety Performance Analysis System (SPAS) utilizing current sources. This data is reviewed by the Principal Inspectors (PI) prior to completing the RSAT.
An RSAT is completed taking into consideration steps 1 and 2, expertise of PI and system design, which includes operating environment, configuration and design of repair station.
The surveillance program is modified to reflect the risk level in each element.
The completed RSAT enables an assessment of the repair station.
An RMP is to be utilized for issues of high concern.
During the next twelve months, the Updated Surveillance Program and RMPs are completed and this data is fed back into the system.
At the beginning of the fiscal year (FY), the process is repeated beginning with step 1 to obtain an overall assessment of the operator and plan surveillance for upcoming year, enabling the FAA to target resources to areas of highest risk.
The flowchart on the next page depicts the above process and the next subsections provide further detail for steps 1 through 6.
