MEMORANDUM FOR A1 - Air Force E-Publishing

52 AFI91-202 5 AUGUST 2011
5.9.2. Commanders can request AFCAST surveys by visiting www.afcast.org. Other
inquiries must be addressed to the HQ AFSC Human Factors Division (HQ AFSC/SEH).
5.10. Organizational Safety Assessment (OSA). OSAs are a proactive, mishap prevention tool
that aids commanders and other leaders in risk assessment and decision making.
5.10.1. The OSA program focuses on operations, maintenance, air traffic control, security
forces and other areas directly related to safety. It assesses and quantifies personnel stress
levels and perceptions. The OSA identifies organizational climate and culture factors with
safety implications and provides base level senior leadership with proven safety
recommendations tailored to specific situations.
5.10.2. Installation-level commanders may request an OSA through the AFSC Human
Factors Division (AFSC/SEH). All requests are approved by AF/SE. HQ AFSC will conduct
the assessment and provide an out-brief to the requesting commander. Contact AFSC/SEHA
DSN 246-3763 for information.
5.11. Standard Mishap Metrics. Mishap metrics (calculated as a number of events against
some kind of exposure) are an effective way to compare the actions and accomplishments of
your unit. Consideration must be given to the differences in operations, environment, equipment
or other variables when comparing organizations or MAJCOMs. The metrics used by the safety
community to this point have focused on results - the number of mishaps experienced over time
relative to exposure. HQ AFSC uses standardized rates for metrics below:
5.11.1. Aviation Mishaps.
5.11.1.1. Total USAF Aviation Class A/B Metric. This metric identifies the number of
USAF aviation mishaps (to include flight, flight related aircraft ground operations and
remotely piloted aircraft [RPA]) and aircraft flight and RPA mishap rates per 100,000
flying hours. The Class A/B rate is calculated as the total number of Class A/B mishaps
multiplied by 100,000 flying hours divided by the total number of flying hours.
5.11.1.2. USAF Class A Aviation Flight Mishap Metric. This metric identifies the
number of USAF Class A aircraft flight mishaps per 100,000 flying hours.
5.11.1.3. Aviation-Related Fatalities Metric. This metric identifies the number of
fatalities due to USAF aviation mishaps and mishap rates per 100,000 flying hours.
5.11.1.4. Destroyed USAF Aircraft Metric. This metric identifies the number of
destroyed USAF aircraft due to aviation mishaps and mishap rates per 100,000 flying
hours.
5.11.1.5. USAF RPA A/B Metric. This metric identifies the number of USAF RPA
mishaps and the RPA mishap rate per 100,000 flying hours.
5.11.1.6. USAF RPA Destroyed Metric. This metric identifies the number of USAF
destroyed RPA and the rate per 100,000 flying hours.
5.11.2. Class A & B Missile and Explosives Metric. This metric identifies the total Class A
and B missile and explosives mishaps.
5.11.3. Class A & B Space Metric. This metric identifies the total Class A and B Space
mishaps.
