A-76-137
NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Until such time as the above provisions of AC 150/5320-12 are made mandatory, require that periodic friction surveys, as outlined in chapter 5 of AC 150/5320-12, be conducted on all runways certificated under 14 CFR 139. Also require that appropriate corrections be taken if unsafe surface conditions exist or that timely cautionary notices, such as NOTAMs, be issued if immediate corrections cannot be made and operational considerations dictate continued use of the runway. (Superseded by A-82-152 through A-82-169) (Urgent)
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to require periodic friction surveys, as described in chapter 5 of AC 150/5320-12, on all runways certificated under 14 CFR 139 until those provisions become mandatory. It must also require that corrections be made if unsafe surface conditions exist, or that timely cautionary notices such as NOTAMs be issued if corrections cannot be made immediately and continued use is operationally necessary.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
