Safety Recommendation History
From: NTSB
To: FAA
Date: 6/7/1994
Response: THE BOARD NOTES THAT THE FAA USED BOTH CONTRACTOR & FAA PERSONNEL TO REVIEW AVIATION SAFETY INSPECTOR (ASI) JOB TASKS & ELEMENTS. THE FAA PERFORMED FURTHER RESEARCH ON ASI STAFFING, ANALYZING JOB TASKS BY TIME & FREQUENCY. AS A RESULT OF THIS STUDY, THE FAA GENERATED PRELIMINARY FIELD OFFICE STAFFING ESTIMATES THAT CAN BE ANALYZED AGAINST CURRENT ON-BOARD EMPLOYMENT TO VALIDATE THE ACCURACY OF THE STAFFING ESTIMATES. ADDITIONALLY, THE FAA PLANS TO PERIODICALLY RUN THE UPDATED ENVIRONMENTAL & CERTIFICATE DATA AGAINST THE MODELS & FORMULAS TO IDENTIFY NEEDED ADJUSTMENTS IN WORK FORCE DISTRIBUTION BY OPTION & SPECIALTY, AS WELL AS BY REGION & FIELD OFFICE. BASED ON THIS INFO, THE BOARD CLASSIFIES A-90-136 "CLOSED--ACCEPTABLE ACTION."

From: FAA
To: NTSB
Date: 2/2/1994
Response: IN PREVIOUS CORRESPONDENCE THE FAA DESCRIBED ITS ACCOMPLISHMENTS IN REVALIDATING ITS AVIATION SAFETY INSPECTOR (ASI) STAFFING STANDARDS & THE DEVELOPMENT OF A PRODUCTIVE STANDARD. THE WORK RESULTED IN STANDARDS DEVELOPED AT THE REGIONAL LEVEL & GENERATED PRELIMINARY FIELD OFFICE STAFFING ESTIMATES THAT CAN BE ANALYZED AGAINST CURRENT ON BOARD EMPLOYMENT TO VALIDATE THE ACCURACY OF STAFFING ESTIMATES. WHILE I BELIEVE THAT THE FAA HAD ADDRESSED THIS RECOMMENDATION COMPLETELY, THE BOARD ASKED FOR MORE SPECIFIC DETAILS ABOUT HOW THE STAFFING STANDARDS WERE CHANGED & HOW POSITIONS ARE ALLOCATED WHEN CERIFICATE COMPLEXITIES CHANGE WITHIN OFFICES & REGIONS.

From: FAA
To: NTSB
Date: 5/11/1993
Response: THE FAA HAS UPDATED THE SAFETY INSPECTOR STAFFING STANDARDS. THE STANDARDS WERE DEVELOPED AT THE REGIONAL LEVEL AND HAVE BEEN APPLIED USING THE MOST CURRENT DATA FROM THE NATIONAL VITAL INFORMATION SUBSYSTEM PROVIDING REGIONAL STAFFING ESTIMATES. PRELIMINARY FIELD OFFICE STAFFING ESTIMATES HAVE ALSO BEEN GENERATED AND ARE PRESENTLY BEING ANALYZED AGAINST CURRENT ON-BOARD EMPLOYMENT TO DETERMINE THE ACCURACY OF THESE ESTIMATES. A FURTHER CONTRACT EFFORT TO INCORPORATE SELF-REPORTING DATA COLLECTED DURING THE DEVELOPMENT OF THE REVISED STANDARDS BEGAN IN APRIL. THIS EFFORT WILL INCREASE THE STATISTICAL ACCURACY OF THE STAFFING STANDARDS AT THE FIELD OFFICE LEVEL. THIS EFFORT WILL ALSO PROVIDE SPECIFIC TRAVEL ALLOWANCES FOR EACH FIELD OFFICE RATHER THAN THE NATIONAL AVERAGE NOW INCORPORATED INTO THE STAFFING STANDARDS.

From: NTSB
To: FAA
Date: 5/11/1993
Response: THE BOARD NOTES THAT THE FAA HAS UPDATED SAFETY INSPECTOR STAFFING STANDARDS USING CURRENT DATA FROM THE NATIONAL VITAL INFORMATION SUBSYSTEM, WHICH PROVIDES REGIONAL STAFFING ESTIMATES. FIELD OFFICE STAFFING ESTIMATES HAVE ALSO BEEN GENERATED AND A FURTHER CONTRACT EFFORT TO INCORPORATE SELF-REPORTING DATA COLLECTED DURING THE DEVELOPMENT OF THE REVISED STANDARDS BEGAN IN ARIL. FURTHERMORE, THE BOARD NOTES THAT THESE EFFORTS WILL INCREASE THE STATISTICAL ACCURACY OF THE STAFFING STANDARDS AT THE FIELD OFFICE LEVEL AND WILL PROVIDE SPECIFIC TRAVEL ALLOWANCES FOR EACH FIELD OFFICE. THE BOARD, HOWEVER, REMAINS CONCERNED ABOUT THE ADEQUACY OF FSDO STAFFING AND GEOGRAPHIC PLACEMENT. THE BOARD WOULD LIKE MORE SPECIFIC DETAILS AS TO HOW THE STAFFING STANDARDS WERE CHANGED AND HOW POSITIONS ARE ALLOCATED WHEN CERTIFICATE COMPLEXITIES INCREASE OR DECREASE WITHIN THE OFFICES AND REGIONS. ADDITIONALLY, THE FAA INDICATED IN PREVIOUS CORRESPONDENCE THAT IT HAD ISSUED A CONTRACT TO STUDY FSDO STAFFING. THE BOARD WOULD LIKE TO REVIEW A COPY OF THE CONTRACTOR'S FINAL REPORT. PENDING RECEIPT AND REVIEW OF THE INFORMATION REQUESTED, THE BOARD CLASSIFIES RECOMMENDATION A-90-136 "OPEN--ACCEPTABLE RESPONSE."

From: NTSB
To: FAA
Date: 2/2/1993
Response: From the aircraft accident report of Tomy International, Inc. doing business as Scenic Air Tours flight 22, Beech model E18S, N342E, in-flight collision with terrain Mount Haleakala, Maui, Hawaii on April 22, 1992.

From: NTSB
To: FAA
Date: 7/31/1992
Response: On February 8, 1991, the FAA responded to this recommendation stating that it had contracted for a study that would revalidate its staffing standards and would include the availability of work hours, geographic areas of responsibility, and the size and complexity of operations. This study was originally scheduled to have been completed in October 1991. Subsequent FAA correspondence on February 11, 1992, indicated that the completion of the study had been delayed. Pending the completion of the study and the FAA's further response. Safety Recommendation A-90-136 will remain classified as "Open--Acceptable Response."

From: NTSB
To: FAA
Date: 3/24/1992
Response: The Safety Board has been aware that the FAA, recognizing the need to revalidate its safety inspector staffing standards, had contracted for a study to be completed by October 1991. We are now informed that the study has been delayed, but when it is completed, the contractor will present the FAA with revised FDSO staffing standards. Pending the FAA's further response, this safety recommendation remains classified as "Open--Acceptable Response."

From: FAA
To: NTSB
Date: 2/11/1992
Response: THE FAA EFFORT TO UPDATE THE SAFETY INSPECTOR STAFFING STANDARDS HAS BEEN DELAYED.

The Board adopted this report on 9/17/1991. Also as a result of its investigation of this accident, the National Transportation Safety Board reiterates Safety Recommendation A-90-136 to the Federal Aviation Administration.

Date: 2/8/1991
Response: THE FAA HAS RECOGNIZED THE NEED TO REVALIDATE ITS SAFETY INSPECTOR STAFFING STANDARD AND HAS PROCURED A CONTRACTOR TO DEVELOP THE REQUIRED ANALYSES AND REVALIDATED STAFFING STANDARD. THIS STAFFING STANDARD SHOULD BE COMPLETED IN OCTOBER 1991. WHEN COMPLETED, THE STANDARD WILL PROVIDE STAFFING DATA APPLICABLE TO INDIVIDUAL DISTRICT OFFICES.
