The FAA found that some small Pilatus airplanes might have a loose part on the seatbelt, which could make it unsafe for the pilot and others on the plane. So, they made a rule that owners must check and fix this to make sure everyone stays safe in the air.
Summary AI
The Federal Aviation Administration (FAA) has issued a new rule for all Pilatus Aircraft Ltd. Model PC-7 airplanes. This rule addresses an identified unsafe condition concerning a missing screw on a harness shoulder strap buckle that could lead to loss of pilot restraint and potential loss of airplane control or crew injury. Effective February 12, 2021, it requires inspections and potential repairs or replacements of the affected parts to ensure safety. The FAA invites comments on this rule until March 29, 2021, and has deemed the situation urgent enough to forgo the usual public comment period prior to enacting the rule.
Abstract
The FAA is adopting a new airworthiness directive (AD) for all Pilatus Aircraft Ltd. (Pilatus) Model PC-7 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as a missing release bar retaining screw on a Harley-type buckle assembly installed on a harness shoulder strap. This condition, if not corrected, could lead to loss of pilot restraint and consequently loss of airplane control or injuries to the crew. The FAA is issuing this AD to address the unsafe condition on these products.

The Federal Aviation Administration (FAA) has released a new airworthiness directive (AD) focusing on Pilatus Aircraft Ltd. Model PC-7 airplanes. This rule stems from a potential safety hazard involving a missing component—specifically, a release bar retaining screw—on a buckle assembly within the pilot's harness. Such an issue could jeopardize pilot restraint, leading to the potential loss of airplane control or injuries to the crew. To mitigate this risk, the FAA has stipulated mandatory inspections and repairs or replacements of the faulty parts, effective February 12, 2021. Interestingly, the urgency of this situation has led the FAA to forgo the typical public consultation process before implementing this rule, although they are still accepting comments up until March 29, 2021.
Significant Issues and Concerns
One notable concern is the absence of clarity regarding the competitive sourcing of the necessary replacement parts. The document does not specify whether there was a bidding process or if Pilatus Aircraft Ltd. is the sole provider, which might raise fairness issues. Additionally, the estimated compliance costs are mentioned in the text, but without detailed explanation or justification, especially in regard to the high cost of replacement parts—reported at $10,000 per seat harness. This could lead to questions about the calculation and allocation of costs.
The document also presents information in complex legal and technical language that may not be easily digestible for a general audience. Such language assumes a familiarity with aviation-specific codes and external documents, which may not be easily accessible or understood by all stakeholders, potentially alienating those who are not experts in the field. Furthermore, procedural details, such as obtaining special flight permits, are not explained in detail, possibly leading to ambiguity or misinterpretation.
Public and Stakeholder Impact
Broadly speaking, the implementation of this AD should enhance air travel safety by addressing a tangible risk associated with the PC-7 airplane model. Passengers, pilots, and crew members directly benefit from the assurance of improved safety protocols and equipment reliability. Therefore, the document aligns with public interests in transportation safety.
On the other hand, the financial implications could negatively impact aircraft operators, who bear the burden of compliance costs. With 21 airplanes identified in the U.S. registry, operators must reckon with inspections and potential part replacements, which could be financially burdensome due to the stated costs. This may particularly impact smaller operators who may not have the financial leeway to absorb such expenses. Moreover, the lack of a bidding process for parts could disadvantage operators by forcing them to purchase potentially overpriced parts from limited sources.
In summary, while the FAA's directive prioritizes public safety, it raises concerns regarding transparency and financial pressure on operators. Ensuring safety in aviation is paramount; however, the fairness in procurement processes and clear communication could be improved to better serve all stakeholders involved.
Financial Assessment
In the Federal Register document, several financial references are made regarding the implementation and compliance costs associated with a new airworthiness directive for Pilatus Aircraft Ltd. Model PC-7 airplanes. An analysis of these financial aspects helps shed light on their implications and possible concerns.
Summary of Financial References
The document outlines the estimated costs for complying with the airworthiness directive (AD) affecting U.S. operators of the Pilatus Model PC-7 airplanes. The Federal Aviation Administration (FAA) estimates the costs as follows:
- The average labor rate is set at $85 per work-hour.
- Based on this rate, the total cost of compliance for all U.S. operators is projected to be $892.50 or $42.50 per product for the initial inspection.
- If repairs are needed, they would take an additional 0.5 work-hour at a cost of $42.50 per seat harness.
- Should full replacement be necessary, it is estimated to take 3 work-hours and require parts costing $10,000, resulting in an overall cost of $10,255 per seat harness.
Relation to Identified Issues
The financial estimates provided raise several considerations:
Lack of Cost Detail: The document mentions a substantial cost of $10,000 for parts required for a full replacement of seat harness components. However, detailed information or justification about what precisely drives this cost is not provided, which could lead to concerns about whether the parts are fairly priced or if there is a risk of financial favoritism towards specific manufacturers.
Simplicity for Clarity: Although the document addresses monetary figures in straightforward terms, some complexity remains in understanding the broader context of these figures without additional background on how these costs were derived. Moreover, the assumption of a standard labor rate of $85 per hour could vary depending on geographical and labor market differences, potentially impacting the real-world applicability of the cost projections.
Accessibility for Stakeholders: Given the technical nature of aviation maintenance and regulations, stakeholders without in-depth industry knowledge might find it challenging to grasp the significance of the financial references without further clarification or context.
Overall, while the financial allocations are clear within the document, a more detailed explanation or breakdown of these costs, specifically regarding replacement parts, might help stakeholders better understand the financial impact on operators and ensure transparency in the estimation process.
Issues
• The document does not explicitly state whether there was any competitive bidding process or multiple sources for the service parts mentioned, which could raise concerns about favoritism towards the manufacturer mentioned.
• The estimated costs of compliance could benefit from more detailed breakdowns or justification, especially regarding the replacement parts costing $10,000.
• The document contains complex legal and technical jargon that may not be easily understood by a general audience without specialized knowledge.
• The document assumes familiarity with specific aviation codes and other referenced documents, which might not be accessible or clear to all stakeholders.
• Certain procedural details, like the process for obtaining special flight permits, could be more explicitly detailed to avoid ambiguity.
