OPNAV INSTRUCTION
3750.21
From: Chief of Naval Operations
Subj: POLICY FOR ADMINISTERING THE BIRD/ANIMAL AIRCRAFT STRIKE
HAZARD PROGRAM IN THE U.S. NAVY
Ref: (a) OPNAVINST 3750.6S
(b) OPNAVINST 5090.1D
(c) DoD Manual 4150.07-V3, DoD Pest Management Training and Certification
Program Manual, 23 May 2013
Encl: (1) Wildlife Management and Control Techniques at CNIC Installation Airfields
1. Purpose. To establish United States Navy Bird/Animal Aircraft Strike Hazard (BASH)
Program policy and assign specific responsibilities for implementing reference (a).
2. Scope and Applicability. This instruction is applicable to all Navy commands that operate
aircraft at shore-based airfields and to other Navy commands that enable or support flight
operations through airspace control, range monitoring, facilities maintenance, natural resources
management, and weapons handling and storage oversight.
3. Background. Many Navy bases around the world are located in areas where wildlife hazards
present significant risks for air and ground strikes from birds and other wildlife. Such strikes can
result in potential loss of life for flight crews or ground personnel, costly aircraft damage, and
degradation of mission capability for Navy installations and their customers. A well-planned and
executed BASH program, structured according to safety management system principles
established in reference (a), provides a proven means for identifying aviation safety hazards and
effectively mitigating the associated risks.
4. Policy. BASH planning will be considered a key component of overall aviation safety risk
management at shore-based airfields. The designated program manager will direct and monitor
an integrated BASH effort among naval aviation stakeholders that comports with the guidelines
established in references (a), (b), and (c), and that is strategically focused to sustain the safest
possible airfield operating environments, enhance fleet operational readiness, and protect limited
Navy resources. Specific objectives of the Navy BASH program are to:
a. Reduce injury to personnel and damage to aircraft and infrastructure resulting from
wildlife strikes through proactive hazard monitoring, evaluation, management, and mitigation.
