AIM 

ATC will not interpret a casual remark to mean that 
a NMAC is being reported. The pilot should state “I 
wish to report a near midair collision.” 

d.  Where to File Reports. 

Pilots and/or flight 

crew members involved in NMAC occurrences are 
urged to report each incident immediately: 

1. 

By radio or telephone to the nearest FAA ATC 

facility or FSS. 

2. 

In writing, in lieu of the above, to the nearest 

Flight Standards District Office (FSDO). 

e.  Items to be Reported. 

1. 

Date and time (UTC) of incident. 

2. 

Location of incident and altitude. 

3. 

Identification and type of reporting aircraft, 

aircrew destination, name and home base of pilot. 

4. 

Identification and type of other aircraft, 

aircrew destination, name and home base of pilot. 

5. 

Type of flight plans; station altimeter setting 

used. 

6. 

Detailed weather conditions at altitude or 

flight level. 

7. 

Approximate courses of both aircraft: 

indicate if one or both aircraft were climbing or 
descending. 

8. 

Reported separation in distance at first 

sighting, proximity at closest point horizontally and 
vertically, and length of time in sight prior to evasive 
action. 

9. 

Degree of evasive action taken, if any (from 

both aircraft, if possible). 

10. 

Injuries, if any. 

f.  Investigation. 

The FSDO in whose area the 

incident occurred is responsible for the investigation 
and reporting of NMACs. 

g. 

Existing radar, communication, and weather 

data will be examined in the conduct of the 
investigation.  When possible, all cockpit crew 
members will be interviewed regarding factors 
involving the NMAC incident. Air traffic controllers 
will be interviewed in cases where one or more of the 

involved aircraft was provided ATC service. Both 
flight and ATC procedures will be evaluated. When 
the investigation reveals a violation of an FAA 
regulation, enforcement action will be pursued.

plained phenomena reporting data collection center, 
such as the National UFO Reporting Center, etc. 

b. 

If concern is expressed that life or property 

might be endangered, report the activity to the local 
law enforcement department.

5.  Safety Alerts For Operators (SAFO) 

and Information For Operators (InFO) 

a. 

SAFOs contain important safety information 

that is often time-critical. A SAFO may contain 
information and/or recommended (non-regulatory) 
action to be taken by the respective operators or 
parties identified in the SAFO. The audience for 
SAFOs varies with each subject and may include: Air 
carrier certificate holders, air operator certificate 
holders, general aviation operators, directors of 
safety, directors of operations, directors of mainten-
ance, fractional ownership program managers, 
training center managers, accountable managers at 
repair stations, and other parties as applicable. 

b. 

InFOs are similar to SAFOs, but contain 

valuable information for operators that should help 
them meet administrative requirements or certain 
regulatory requirements with relatively low urgency 
or impact in safety. 

c. 

The SAFO and InFO system provides a means 

to rapidly distribute this information to operators and 
can be found at the following website:

airline_operators/airline_safety/safo 

and

airline_operators/airline_safety/info 

or search keyword FAA SAFO or FAA INFO. Free 
electronic subscription is available on the “ALL 
SAFOs” or “ALL InFOs” page of the website.
