Safety Recommendation History
From: NTSB
To: FAA
Date: 1/9/1990
Response: Safety Recommendation A-88-98 concerns information conveyed to principal maintenance inspectors (PMI) and principal operations inspectors (POI) about turbopropeller airplanes. The Safety Board accepts the FAA statement that the December 13, 1988, maintenance alert pertained to all turbopropeller aircraft, not to just the CASA C- 212, which is the subject of the alert. Based on the clarification of the intended subject of the maintenance alert, the Safety Board has classified Safety Recommendation A-88-98 as "Closed--Acceptable Action."

Response: THE FAA MAINTENANCE ALERT REQUESTING THAT ALL PRINCIPLE MAINTENANCE AND OPERATIONS INSPECTORS EMPHASIZE, DURING THEIR SURVEILLANCE OF OPERATORS OF TURBORPROPELLOR AIRCRAFT, THE NEED TO ADHERE TO PRESCRIBED MANUFACTURER FLIGHT IDLE BLADE ANGLES, WAS APPLICABLE TO ALL TURBOPROPELLOR AIRPLANES, AS STATED IN ITS TEXT.

Date: 5/19/1989
Response: Safety Recommendation A-88-98 concerns information conveyed to principal maintenance inspectors (PMI) and principal operations inspectors (POI) about turbopropeller airplanes. Knowledge of adjustment of blade pitch angles (especially the need for keeping the blade angles alike, actuation within tolerances, etc.) and the need to follow manufacturer's instructions are basic requirements for any person obtaining an airframe and powerplant mechanic license. The investigations of the CASA-212 airplane accidents found that, in both cases, the mechanics were not following the maintenance instructions. The actuation and design of the propellers on the Garrett engines used in the CASA-212 are similar to those used in many other turbopropeller airplanes; therefore, the safety recommendation addresses all turbopropeller airplanes. The subject line of the FAA's maintenance alert issued as a response to this safety recommendation addressed only CASA-212 airplanes, not all turbopropeller aircraft as recommended. While the PMIs and POIs may discuss this maintenance problem with operators of other turboprop aircraft, the maintenance alert does not specifically require the inspectors to do so. Therefore, while the Safety Board appreciates the FAA's issuing the maintenance alert, we believe it does not fully satisfy the safety recommendation. The Safety Board requests that the FAA issue a maintenance alert specifically stating that the alert applies to all turbopropeller airplanes. Safety Recommendation A-88-98 is classified as "Open--Acceptable Action" pending your further response.

Response: THE FAA ISSUED A MAINTENANCE ALERT REQUESTING THAT ALL PRINCIPLE MAINTENANCE AND OPERATIONS INSPECTORS EMPHASIZE, DURING THEIR COPY OF THE ALERT FOR THE BOARD'S INFORMATION. I CONSIDER THE FAA'S ACTION TO BE COMPLETED.
