1. MORE Instructions For Continued Airworthiness Left mouse click to move to next slide.

2. BACKGROUND There are a total of eight MORE STCs applicable to thirty different models of Pratt & Whitney Canada PT6A Series engines. The STCs are designed to require the engine to meet a specified initial entry condition. The engine’s condition shall be continually monitored there after and maintained through specific inspections, maintenance tasks, and on condition monitoring. The MORE STCs are approved FAR 33.4 Instructions for Continued Airworthiness (ICA) intended to supplement specific sections of the Pratt & Whitney Canada (P&WC) PT6A maintenance manual.

3. Use of these Instructions for Continued Airworthiness (ICA) provides for hot section inspection (HSI) interval on condition and time between overhaul (TBO) interval to 8000 hours. The ICA supersedes the need for compliance with the HSI and TBO intervals defined in P&WC PT6A Service Bulletin Number 1003.

4. How it works The MORE STCs require an on-condition monitoring system that includes: repetitive inspections, oil and oil filter analysis, engine performance checks, borescope inspections, and vibration analysis as some of it’s major components.

5. GENERALINTRODUCTION The MORE Instructions for Continued Airworthiness are a set of directions for maintaining the aircraft engine in a safe and durable condition. The MORE Instructions for Continued Airworthiness provide an aggressive repetitive inspection system.

6. The purpose of the inspections, which are included in the MORE Instructions For Continued Airworthiness, is to look for problems in the engine. When problems are found, they are to be corrected promptly. After the problem is corrected the engine may return to flying status.

7. GENERALINTRODUCTION(continued) The engine is subjected to an Initial Entry Inspection. This inspection is used to determine the condition of the engine and to initialize the engine with respect to the MORE STC.

8. GENERALINTRODUCTION(continued) After the engine has completed the “Initial Entry Inspection”, there are repetitive (periodic) checks and inspections which must be performed.

9. GENERALINTRODUCTION(continued) The Initial Entry Inspection establishes baselines that are used for comparison evaluations at each additional inspection interval, so that the health, and changes to the health of the engine can be determined.

10. GENERALINTRODUCTION(continued) A “MORE Scheduled Inspection Status Sheet” is provided with each STC. It describes those tasks that need to be performed, it states when the tasks where last performed and when they need to be repeated. These inspections are to be recorded in terms of TSO.

11. GENERALINTRODUCTION(continued) A “MORE Scheduled Inspection Status Sheet” is also provided in an electronic spreadsheet format, using Microsoft Excel. A printed copy of this spreadsheet should be maintained in the engine records.

12. GENERAL INTRODUCTION (continued) Engines using MORE Instructions for Continued Airworthiness must still comply with all applicable Federal Aviation Administration Airworthiness Directives. The rotor component service lives defined in P&WC S/B 1002, latest revision, are to be complied with, and are not superseded by the module repair intervals defined in the MORE STC. P&WC S/B 1002 applies to the largest number of engine models, but P&WC S/B 1302, 1402, 3002, 12002, and 12102 apply to some engine models using the MORE Instructions for Continued Airworthiness.

13. The procedures should include but are not limited to: a. How the operator will ensure compliance with the requirements of the STC. b. The title of the person(s) responsible for performance of the various elements of the STC. c. The name of the person(s) responsible for the STC management. d. The procedures for recognition of adverse trends and revision of inspection frequencies or requirements resulting from maintenance findings. e. When adverse trends are recognized the objective is to shorten inspection intervals and / or to tighten inspection requirements in order to more closely monitor the engine and to prevent deterioration from progressing to an unsafe condition.

14. Operators must maintain all records and reports necessary to demonstrate continued compliance with the MORE STC.
