FAA Part 135 Explained

When considering private charter flights, understanding the regulatory framework that governs these operations is crucial for making informed decisions. Among the most important regulations is FAA Part 135, which sets the standards for commercial aviation operations in the United States. For private charter clients, this regulation directly impacts safety, service quality, and operational reliability.

What is FAA Part 135?

FAA Part 135 is a section of the Federal Aviation Regulations (FARs) that governs commercial aviation operations, specifically non-scheduled air carrier and commercial operator operations. This regulation applies to aircraft operators who provide air transportation services to the public, including charter flights, air taxi services, and cargo operations.

The regulation was established to ensure that commercial aviation operations maintain the highest safety standards while providing flexibility for non-airline commercial flights. Unlike Part 121, which governs major airlines with scheduled passenger service, Part 135 covers smaller-scale commercial operations that typically use aircraft with 30 or fewer passenger seats or a maximum payload capacity of 7,500 pounds or less.

Key Requirements Under FAA Part 135

Operating Certificate Requirements

To operate under Part 135, companies must obtain an Air Carrier Certificate and Operations Specifications from the FAA. This process involves extensive documentation, safety management systems, and operational procedures. The certification process typically takes 6-12 months and requires operators to demonstrate their ability to conduct safe commercial operations.

Pilot Qualifications and Training

Part 135 establishes stringent pilot qualification requirements that exceed those for private flying:

  • Minimum Flight Hours: Pilots-in-command must have at least 1,200 total flight hours, including 500 hours of cross-country flight time and 100 hours of night flight time
  • Instrument Rating: All pilots must hold an instrument rating
  • Recurrent Training: Pilots must complete recurrent training every 12 months, including simulator training and proficiency checks
  • Medical Certificates: Pilots must hold at least a second-class medical certificate

Aircraft Maintenance Standards

Part 135 operators must adhere to rigorous maintenance requirements:

  • Inspection Programs: Aircraft must follow approved inspection programs with more frequent checks than private aircraft
  • Maintenance Records: Comprehensive maintenance tracking and documentation
  • Authorized Repair Stations: Maintenance must be performed by certified repair stations or appropriately licensed mechanics

Operational Limitations and Safety Measures

The regulation establishes specific operational limitations designed to enhance safety:

  • Weather Minimums: More restrictive weather minimums than private operations
  • Duty Time Limitations: Strict limits on pilot duty and flight time to prevent fatigue
  • Equipment Requirements: Enhanced equipment requirements including weather radar, emergency equipment, and navigation systems

How Part 135 Affects Private Charter Clients

Enhanced Safety Standards

For private charter clients, Part 135 operations offer significantly enhanced safety compared to private aircraft operations. According to the National Transportation Safety Board (NTSB), commercial aviation under Part 135 has a substantially lower accident rate than general aviation. The comprehensive training requirements, maintenance standards, and operational procedures create multiple layers of safety protection.

Professional Service Standards

Part 135 operators must maintain professional standards that directly benefit clients:

  • Crew Resource Management: Pilots receive training in communication, decision-making, and crisis management
  • Customer Service: Professional flight crews trained in passenger service and emergency procedures
  • Operational Reliability: Standardized procedures that enhance on-time performance and operational consistency

Regulatory Oversight

Unlike private aircraft operations, Part 135 operators are subject to regular FAA oversight:

  • Routine Inspections: FAA inspectors conduct regular inspections of operations, maintenance, and training programs
  • Compliance Monitoring: Continuous monitoring of operational compliance with safety regulations
  • Corrective Action: Immediate corrective action requirements when deficiencies are identified

Comparing Part 135 to Other Aviation Regulations

Part 135 vs. Part 121 (Airlines)

While Part 121 governs major airlines, Part 135 offers several advantages for charter clients:

  • Flexibility: No fixed schedules, allowing departure times to match client needs
  • Airport Access: Can operate from smaller airports not served by airlines
  • Personalized Service: Smaller aircraft and dedicated crew attention
  • Privacy: Exclusive use of aircraft without other passengers

Part 135 vs. Part 91 (Private Operations)

Part 91 governs private aircraft operations, which differ significantly from Part 135:

  • Safety Standards: Part 135 requires higher safety standards and more rigorous training
  • Pilot Qualifications: More stringent pilot experience and training requirements
  • Maintenance: More frequent and comprehensive maintenance requirements
  • Operational Oversight: Regular FAA oversight versus minimal oversight for private operations

Cost Implications of Part 135 Operations

Operating Costs

Part 135 operations typically cost more than private aircraft operations due to:

  • Enhanced Training: Comprehensive pilot training programs
  • Maintenance Requirements: More frequent and detailed maintenance procedures
  • Insurance: Higher insurance requirements and costs
  • Regulatory Compliance: Costs associated with maintaining FAA certification

Value Proposition

Despite higher costs, Part 135 operations offer significant value:

  • Safety: Substantially lower accident rates than private operations
  • Reliability: Professional maintenance and operational standards
  • Peace of Mind: Regulatory oversight and compliance monitoring
  • Service Quality: Professional crew training and customer service standards

Choosing a Part 135 Operator

Due Diligence Factors

When selecting a Part 135 charter operator, clients should consider:

  • Safety Record: Review the operator's safety history and accident record
  • Fleet Age and Type: Evaluate aircraft age, maintenance history, and suitability for your mission
  • Pilot Qualifications: Verify pilot experience and training records
  • Insurance Coverage: Confirm adequate insurance coverage for passengers and aircraft
  • Operational History: Research the operator's track record and customer reviews

Questions to Ask Potential Operators

  • What is your safety management system?
  • Can you provide references from recent clients?
  • What are your pilot minimum experience requirements?
  • How often do you conduct recurrent training?
  • What is your maintenance inspection schedule?
  • Are your pilots typed and current in the aircraft I'll be flying?
