Safety Recommendation A-01-077

The FAA redesigned the General Aviation (GA) Survey in 2002 and 2003 to address the concerns of different groups using the survey. The redesigned survey clarified the measurement of aircraft use and differentiated among flight purposes. These revisions satisfy Safety Recommendation A-01-77, which is classified CLOSED – ACCEPTABLE ACTION.

CC# 201100023: - From J. Randolph Babbitt, Administrator: These recommendations were issued to improve the FAA's annual General Aviation and Air Taxi Activity Survey (GA Survey), now called General Aviation and Part 135 Activity Survey. The need for these improvements was principally identified through the work of the General Aviation Data Improvement Team (GADIT), which is a sub-team of the General Aviation Joint Steering Committee (GAJSC), and is co-chaired by the National Transportation Safety Board (NTSB), General Aviation Manufacturers Association (GAMA), and FAA.

The GAJSC was formed as part of the Safer Skies Focused Safety Agenda (initially launched in 1998), and is the primary vehicle for government-industry cooperation, communication, and coordination on GA accident mitigation. In order to establish goals for accident reduction and to measure the effectiveness of accident mitigations, general aviation accidents need to be measured as a rate instead of simple accident counts. The GA Survey is the primary vehicle to measure GA activity, but confidence in its accuracy, at the time the recommendations were issued, was low.

In order to implement the improvements envisioned by the GADIT, in 2004 the responsibility of the GA Survey moved to the FAA's Office of Accident Investigation, funding was increased and the sample size increased from 30,000 in 2003 to 84,500 in 2004. These changes allowed the survey to target segments of general aviation for which confidence in the data was particularly low. The improvements were made through annual revisions to the survey in coordination with the Board's staff through the GADIT, which they continue to co-chair. Results from the revised 2004-2008 surveys show consistently improved data, with much higher confidence among both government and industry users.

As additional data requirements arise, revisions will continue in coordination with the Board through the GADIT. Issues related to these safety recommendations were initially addressed in a survey redesign workshop conducted under the direction of the Office of Policy and Plans in December 2002. The 2002-2003 GA Survey redesign effort was motivated by the concerns and recommendations of key stakeholders and end user groups, including the GADIT Activity Task Group and the Board’s staff.

Specifically, GADIT, the Board's staff, and other groups using the GA Survey data believed the aircraft use survey items or categories: • Were not mutually exclusive; • Captured multiple dimensions oft1ying (e.g., flight purpose and flight task); • Had unclear or confusing definitions; • Were not consistent with the way other agencies measure flight purpose; and • Did not meet some of the analytic needs of the end-users of the data. The redesigned survey clarified the measurement of aircraft use (or

The FAA has stated that it agrees that improvements should be made to the General Aviation, Air Taxi and Avionics Survey (GAATAS) and that it is working with a group of industry and government representatives (including Safety Board representatives) to produce a detailed implementation plan to address the issues noted by the safety recommendations. The Safety Board appreciates the FAA's efforts to improve the activity survey form and is committed to working with you to make the improvements.

The FAA has stated that it will meet with the General Services Administration (GSA) to harmonize the definitions of public use aircraft and public use flight operations with GSA data collection activities. The Safety Board would appreciate having the opportunity to review the changes agreed upon by both agencies.

Regarding Safety Recommendation A-01-75, the FAA states that it agrees with the intent of this recommendation and in January 2002 began efforts to establish a two-person team of legal instruments examiners to improve currency and accuracy of the data in the Civil Aircraft Registry. The FAA reports that the legal instruments examiners will focus on the aircraft in "sale reported" and "registration pending" status, as well as aircraft with a status code denoting "non-useable addresses." The Safety Board concurs that these potential improvements are an important undertaking, and looks forward to reviewing the progress of this action.

Accordingly, Safety Recommendations A-01-73 thru -80 are classified OPEN -- ACCEPTABLE RESPONSE pending completion of the recommended actions.

Letter Mail Controlled 01/29/2002 4:07:36 PM MC# 2020092 - From Jane F. Garvey, Administrator: The Federal Aviation Administration (FAA) agrees that improvements should be made to the General Aviation, Air Taxi and Avionics Survey (GMTAS). The FM has been working through the past year with a group of government and industry representatives (including representatives from the Safety Board) to identify and prioritize specific improvements to the survey instrument and survey processes. This project is being conducted under the sponsorship of the Safer Skies initiative, and the working team is known as the General Aviation Data Improvement Team (GADIT).

The current status of this project is that the FAA, government, and industry representatives from the GADIT have submitted recommendations for improving the GMTAS to the Joint Steering Committee for Safer Skies. The combined GADIT has subsequently developed some preliminary implementation approaches, with accompanying high-level resource estimates for accomplishing the various items. The FAA will seek feedback on the selected approaches from the Safer Skies Joint Steering Committee at its January meeting. After that, the FAA will determine specific resource requirements and sources for those resources.

A detailed implementation plan will be published after FAA, other government, and industry representatives confirm their resource commitments for the implementation process. The FAA will fold the Board's safety recommendations to improve activity estimates for public use aircraft into the detailed implementation plans being developed for similar improvements suggested by the GADIT. The details of specific changes to the survey instrument and survey process may differ somewhat from the specifics contained in the Board's safety recommendations.

However, the FM believes improvements to the GAATAS will result in better activity estimates for all segments of the target population, including public use aircraft. The FAA also agrees that definitions of public use aircraft and public use flight operations should be harmonized with data collection activities conducted by the General Services Administration. To that end, the FM will meet with representatives from the General Services Administration in January to determine what changes would be appropriate for either agency to make. I will keep the Board informed of the FAA's progress on these safety recommendations.
