Core Responsibilities

Primary Functions

Conduct comprehensive scheduled and unscheduled maintenance, inspections, and repairs on helicopter airframes, engines (piston and turbine), and associated components in strict accordance with FAA regulations and manufacturer's maintenance manuals.
Perform detailed 50-hour, 100-hour, and annual inspections, as well as major airframe and engine overhauls, ensuring all systems meet or exceed established airworthiness standards.
Diagnose, troubleshoot, and rectify complex mechanical, hydraulic, pneumatic, and electrical system discrepancies using advanced diagnostic tools, schematics, and technical documentation.
Execute intricate maintenance tasks specific to rotary-wing aircraft, including main and tail rotor tracking and balancing, transmission and gearbox servicing, and flight control rigging.
Complete major and minor repairs and alterations to aircraft structures, including sheet metal and advanced composite materials, ensuring structural integrity is maintained.
Install, test, and troubleshoot sophisticated avionics systems, including navigation, communication, and flight control systems, ensuring seamless integration and functionality.
Meticulously document all maintenance performed, parts used, and corrective actions taken in aircraft logbooks and digital maintenance tracking systems to ensure a complete and auditable service history.
Interpret and apply Airworthiness Directives (ADs), Service Bulletins (SBs), and other technical data from regulatory bodies and manufacturers to maintain fleet compliance.
Perform engine performance checks, including power assurance checks and trend monitoring, to assess engine health and predict potential issues.
Maintain and service essential aircraft components such as landing gear, brakes, fuel systems, and environmental control systems.
Respond to and resolve Aircraft on Ground (AOG) situations with urgency, often in high-pressure environments, to return aircraft to service safely and efficiently.
Ensure all work is accomplished with the highest standards of safety, cleanliness, and professionalism, maintaining a safe and organized work environment.
Review and sign off on work performed by junior technicians, providing mentorship and ensuring all tasks are completed to the required standard.
Conduct pre-flight and post-flight inspections to identify any potential issues that may have arisen during flight operations.
Manage and maintain all calibrated tools and ground support equipment (GSE), ensuring they are in good working order and certification is current.
Assist in the preparation of aircraft for specific missions, including the installation and removal of mission-specific equipment (e.g., hoists, cameras, medical interiors).
Perform functional check flights and ground runs in collaboration with pilots to verify the correct operation of systems following maintenance.
Order, receive, and inspect aircraft parts and materials to ensure they are the correct type, are free from damage, and have the proper certification paperwork.
Maintain a current and comprehensive understanding of Federal Aviation Regulations (FARs) pertaining to aircraft maintenance and airworthiness.
Interface with pilots and flight crews to debrief on aircraft performance and troubleshoot reported discrepancies, fostering a collaborative and safety-focused culture.

Secondary Functions

Support the movement and ground handling of aircraft within the hangar and on the flight line.
Contribute to the continuous improvement of maintenance procedures and safety management systems (SMS).
Assist in managing the inventory of spare parts, consumables, and specialized tooling.
Provide technical guidance and on-the-job training to apprentice engineers and less experienced technicians.
