Section 139.337 Wildlife hazard management.
(a) In accordance with its Airport
Certification Manual and the requirements of this section, each certificate
holder must take immediate action to
alleviate wildlife hazards whenever

must ensure that a wildlife hazard assessment is conducted when any of the
following events occurs on or near the
airport:
(1) An air carrier aircraft experiences
multiple wildlife strikes;

(2) An air carrier aircraft experiences
substantial damage from striking wildlife. As used in this paragraph, substantial damage means damage or
structural failure incurred by an aircraft that adversely affects the structural strength, performance, or flight
characteristics of the aircraft and that

replacement of the affected component;
(3) An air carrier aircraft experiences
an engine ingestion of wildlife; or
(4) Wildlife of a size, or in numbers,

in paragraphs (b)(1), (b)(2), or (b)(3) of

to any airport flight pattern or aircraft
movement area.
(c) The wildlife hazard assessment required in paragraph (b) of this section
must be conducted by a wildlife damage management biologist who has professional training and/or experience in
wildlife hazard management at airports
or an individual working under direct
supervision of such an individual. The
wildlife hazard assessment must contain at least the following:
(1) An analysis of the events or circumstances that prompted the assessment.
(2) Identification of the wildlife species observed and their numbers, locations, local movements, and daily and
seasonal occurrences.
(3) Identification and location of features on and near the airport that attract wildlife.
(4) A description of wildlife hazards
to air carrier operations.
(5) Recommended actions for reducing identified wildlife hazards to air
carrier operations.
(d) The wildlife hazard assessment required under paragraph (b) of this section must be submitted to the Administrator for approval and determination of the need for a wildlife hazard
management plan. In reaching this determination, the Administrator will
consider - 
(1) The wildlife hazard assessment;
(2) Actions recommended in the wildlife hazard assessment to reduce wildlife hazards;
