Part 135 certificate holders are required to operate under an FAA-approved training program in accordance with 14 CFR §135.323. This program forms the basis for how initial, recurrent, and qualification training is conducted and evaluated. The associated checking requirements, which are: competency checks under §135.293, instrument proficiency checks under §135.297, and line checks under §135.299, are evaluated not only for individual pilot performance but also for adherence to the approved program structure.
During FAA oversight, inspectors are not evaluating training events in isolation. They are assessing whether the training being delivered reflects the approved curriculum and whether the program is being executed as designed. Findings emerge when there is a disconnect between what is approved and what is actually being conducted, even when individual training events appear complete on the surface.
One of the more common areas where discrepancies arise is in the alignment between the approved training curriculum and the training being delivered. These issues are not always the result of intentional deviation but are often introduced through operational complexity, particularly when multiple training providers or internal systems are involved.
A recurring example involves inconsistencies in course or curriculum naming. When training provider records use different naming conventions than those reflected in the FAA-approved training manual, it can create confusion during audits or reviews. For example, a course labeled differently in a training provider’s system than in the approved manual may still represent the same training content, but the lack of alignment can delay validation.
Other issues in this area follow similar patterns. Scenario-based elements may be omitted or substituted without documentation, required maneuvers may not be fully recorded during §135.293 or §135.297 events, and generalized lesson plans may not fully reflect aircraft-specific requirements. In some cases, recurrent cycles are compressed due to scheduling constraints, resulting in incomplete coverage of required elements.
These discrepancies are typically identified when training records are compared directly against the approved curriculum. Even when training is being conducted with the correct intent, the absence of alignment in documentation and structure can create avoidable findings.
Tracking recurrent training cycles under Part 135 introduces another layer of complexity, particularly when multiple requirements must be managed simultaneously. The 12-calendar-month interval defined under §135.351 must be applied consistently across competency checks, instrument proficiency checks, and line checks, each of which carries distinct requirements.
A common issue arises in how recurrent cycles are tracked when training is completed early within an allowable grace period. While early completion is permitted, the original base month remains the anchor point for future tracking. When tracking systems incorrectly reset the base month based on early completion, subsequent training cycles can become misaligned with regulatory requirements.
Additional complications occur when pilots are qualified on multiple aircraft. In these cases, line check scheduling must reflect appropriate rotation between aircraft types. When that rotation is not properly maintained, the issue may not be immediately visible but can surface during audit or surveillance.
Manual tracking systems further increase the likelihood of discrepancies, particularly when there is no independent verification process in place. Even when training events are completed as required, incomplete or inconsistent recordkeeping can create the appearance of non-compliance.
Observed tracking discrepancies include:
In each case, the underlying issue is not the absence of training, but the integrity of how that training is tracked and documented over time.
Checkride events often reveal underlying program weaknesses that may not be apparent through documentation review alone. During competency and proficiency checks, inspectors and check airmen are evaluating both performance and the structure of the evaluation itself.
Incomplete maneuver documentation remains a frequent finding, particularly when required elements are performed but not properly recorded. Similarly, briefing elements may be omitted or inconsistently documented, which can create gaps in the evaluation record.
Differences between simulator-based and in-aircraft evaluations also influence how findings are identified. In a simulator environment, the evaluator has full visibility into the training scenario and can control conditions to ensure all required elements are addressed. In contrast, in-aircraft evaluations introduce real-world variables such as air traffic control, weather, and operational constraints. These factors can influence both the conduct of the check and the evaluator’s ability to observe all required elements.
Standardization among check airmen presents another area where variation can occur. This is most often seen in smaller departments where a limited number of evaluators may apply slightly different emphasis or technique when conducting checks. These differences are typically experienced operationally by line pilots rather than formally identified during FAA oversight. Without structured internal alignment, variation in evaluation approach can persist over time.
In addition, when performance deficiencies are identified during a check, the absence of clearly documented remedial training can create further exposure. Even when corrective action is taken, it must be properly recorded to demonstrate that the training program is functioning as intended.
Common observations during check events include:
Beyond individual events, certain findings originate from how the training program is structured and maintained over time. As operations evolve, training programs must be updated to reflect changes in aircraft configuration, operational procedures, and equipment.
When training manuals are not synchronized with current syllabi or operational practices, inconsistencies begin to develop. These may not be immediately apparent but can accumulate as revisions are made in one area without corresponding updates elsewhere. Over time, this can result in a training program that is technically approved but no longer fully representative of actual operations.
The absence of internal audit mechanisms further increases this risk. Without periodic review, discrepancies in lesson plans, documentation, and execution can persist undetected. Reliance on historical approval, rather than current conformity, is a common factor in these situations.
Effective document control is also critical. When revisions to lesson plans or training materials are not consistently managed, it becomes difficult to ensure that all training events are being conducted against the same standard.
Maintaining alignment between the approved training program, training execution, and supporting documentation is an ongoing requirement within Part 135 operations. This alignment is typically reflected through periodic internal reviews of curriculum content, verification of recurrent tracking logic, and consistency between training manuals and current aircraft configuration.
Standardization among check airmen is generally maintained through internal coordination and alignment of evaluation criteria, particularly in smaller departments where variation can develop more easily. Differences in evaluation approach may persist where these discussions are informal or infrequent.
Documentation review activity is commonly conducted in advance of FAA surveillance or check events, allowing discrepancies between records, manuals, and execution to be identified and resolved prior to external evaluation.
Training program findings in Part 135 environments are rarely tied to a single failure. They more often reflect small inconsistencies that develop over time between approved structure and actual execution. Where alignment across these elements is maintained, oversight activity tends to proceed with fewer interruptions or corrective findings.
Alignment issues within Part 135 training programs are most often identified during FAA surveillance, checkrides, or targeted audits, particularly when discrepancies exist between curriculum structure, recurrent tracking, and supporting documentation. These findings are typically identified through cross-review of training records, manuals, and check event documentation rather than a single isolated deficiency.
When inconsistencies exist between course naming, base month tracking, and documented completion of required training events, they become visible during FAA evaluation and must be addressed before oversight activity can proceed. These conditions are often identified at the point of review rather than during routine internal tracking.
A structured alignment review focused on curriculum consistency, recurrent tracking accuracy, and documentation synchronization provides a clear basis for evaluating whether the training program reflects current operations and the FAA-approved structure. This type of review is commonly conducted in advance of FAA surveillance or check events, or when discrepancies begin to appear between training records and program documentation. Where alignment is confirmed in these areas, exposure to findings during checkrides and recurrent training cycles is reduced.
When FAA surveillance, checkride activity, or internal audit exposure is approaching, discrepancies in curriculum naming, recurrent tracking logic, or training documentation typically indicate the need for a formal alignment review. These elements are evaluated together during oversight and must present a consistent training program structure across manuals, records, and execution.
A structured review of training program alignment which is focused on curriculum consistency, base month tracking accuracy, and documentation alignment, provides a clear basis for confirming that the program reflects current operations and the FAA-approved framework. Sky Safety Solutions supports Part 135 operators in conducting these alignment reviews to ensure training programs are consistent across all evaluated areas prior to FAA oversight.
