This notice provides information to aviation safety inspectors (ASI)
on diesel exhaust fluid (DEF) contaminations of aircraft and outlines the procedures ASIs are to
use after an incident has occurred. This notice also alerts and advises ASIs and foreign Civil
Aviation Authorities (CAA) of events in which aircraft were refueled with jet fuel contaminated
with DEF or were serviced with refueling equipment that was exposed to DEF.

This notice provides guidance regarding policy revisions to the
initial certification process for a Title 14 of the Code of Federal Regulations (14 CFR) part 135
single-pilot applicant.

November 1991, the Flight Standards Service (FS) Quality Management Council (QMC)
chartered a quality action team (QAT) to design and implement an honorary recognition process
for the FS organization. The team developed the prototype guide for the Flight Standards
Recognition System (FSRS) and the process was put in place.
It is important that all FS employees know that this awards system is employee-managed.
Throughout each year, office coordinators meet to discuss the employee recommendations and
determine program direction. The results of those meetings were the basis for the development of
this document. All employees at all levels in the organization may participate in this dynamic
and unique process. You can submit nominations at any time.
FS employees excel at doing their jobs. I encourage everyone to take advantage of this
opportunity to honor the achievements of their coworkers.
