When does an aerospace dispute call for an expert witness?

An aerospace expert becomes necessary when a case depends on whether an aircraft component, system, or design performed as engineered, such as in accident investigations, component failure claims, or disputes over certification compliance. Patent and contract specification disputes involving aerospace technology also typically require expert technical analysis.

What issues can an aerospace expert analyze or opine on?

These experts can evaluate aircraft structural and systems design, propulsion and flight dynamics, failure analysis following an accident or component malfunction, and compliance with aviation safety and certification standards. In patent matters, they can also assess the technical function and scope of the aerospace technology at issue.

What qualifications matter when selecting an aerospace expert for the assignment?

Relevant qualifications include direct engineering experience with the specific aircraft system or component at issue, whether structural, propulsion, or avionics, along with familiarity with FAA or military certification standards where applicable. Prior work with recognized aerospace manufacturers and a record of technical publication add further weight.

How does an aerospace expert support liability and causation arguments?

The expert can reconstruct how a component or system failure occurred using flight data, maintenance records, and engineering analysis, establishing or challenging the causal chain between the alleged defect and the incident. This analysis also supports damages calculations in both accident litigation and commercial disputes over system performance.

How does Round Table Group identify the right aerospace expert for a case?

We begin by working with counsel to define the specific engineering or certification question the case presents, then source and speak with candidates whose systems experience matches that need. After assessing directly relevant experience, confirming interest and availability, and completing conflict checks, we present qualified options to counsel.

Defective Turbine Blade Casting Triggers Engine Manufacturer Indemnification Fight

An engine manufacturer sued its longtime turbine blade casting supplier after a batch of high-pressure turbine blades exhibited premature cracking during in-service inspections, forcing an unscheduled fleet-wide inspection program and engine removals that cost the manufacturer significantly in inspection logistics, loaner engines, and airline compensation. The manufacturer retained an aerospace expert with materials engineering and turbine design experience to review the casting supplier's foundry process records, grain structure analysis of returned blades, and the applicable casting specification. The expert found that the supplier had altered its directional solidification cooling rate during a furnace upgrade roughly a year before the affected blades were cast, producing a grain structure outside the specification's allowable range and consistent with the observed cracking. That finding established the supplier's departure from the qualified casting process and was central to a settlement in which the supplier funded the majority of the inspection and remediation program.

Borescope Inspection Records Anchor a Negligent Maintenance Claim Against an MRO

A regional airline sued the maintenance, repair, and overhaul provider it had contracted to perform heavy engine maintenance after an engine suffered an in-flight shutdown attributed to an improperly torqued fan blade retention system, an event that forced an emergency landing and grounded the aircraft for repairs, in a dispute over repair costs, lost revenue, and regulatory findings. The airline retained an aerospace expert with engine overhaul and maintenance practices experience to review the MRO's work order documentation, torque wrench calibration records, and the engine manufacturer's approved maintenance manual procedures. The expert found that the work order for the fan blade retention system had been signed off without the required torque verification step being separately documented, a deviation from both the manual and the MRO's own quality procedures. That documentation gap was decisive in establishing the MRO's negligence and supported the airline's recovery of the bulk of its repair and downtime costs.

Composite Layup Comparison Anchors a Wing Structure Patent Verdict

An aerospace structures manufacturer sued a competitor alleging that its newly certified composite wing spar design infringed patents covering a specific fiber layup and resin infusion sequence developed to reduce weight while maintaining fatigue life, in a dispute affecting a valuable program over its production run. The plaintiff retained an aerospace expert with composite materials and structural design experience to compare the accused spar's ply schedule and fiber orientation, reconstructed through destructive sectioning of a sample part, against the patent claims and the plaintiff's own manufacturing process. The expert found the accused part's ply sequence and fiber orientation angles matched the patented layup pattern within the tolerances the patent claimed, despite the competitor's public description of an independently developed process. That technical comparison supported the jury's infringement finding and contributed to a damages award calculated on a reasonable royalty basis.

Schedule Delay Root-Cause Analysis Resolves a Prime-Subcontractor Dispute

A prime defense contractor sued a key avionics subcontractor after repeated delivery delays on a military aircraft upgrade program pushed completion more than a year behind schedule, triggering government-imposed penalties and significant cost overruns that the prime sought to pass through to the subcontractor. The subcontractor retained an aerospace expert with program management and systems integration experience to construct a critical path schedule analysis using the program's baseline schedule, change order history, and monthly status reports from both parties. The expert found that roughly 60 percent of the schedule slip traced to late and repeatedly revised interface control documents that the prime contractor itself had been responsible for delivering, while the subcontractor's own deliverables had experienced comparatively minor delays. That schedule apportionment substantially reduced the subcontractor's exposure and was central to a settlement allocating penalty costs largely back to the prime contractor.

Return Condition Survey Resolves an Aircraft Lease-End Dispute

An aircraft lessor sued the airline lessee at the end of a twelve-year lease term, alleging the aircraft was returned in a condition well below the lease's contractual return standards and seeking significant compensation to cover deferred maintenance, corrosion remediation, and interior refurbishment. The airline retained an aerospace expert with aircraft maintenance and airworthiness records experience to review the aircraft's maintenance status, the lease's specific return condition provisions, and the lessor's inspection findings against the fleet-wide condition of comparable aircraft the airline had operated. The expert found several of the items the lessor cited fell within the lease's defined normal wear and tear allowance, and that the aircraft's logged maintenance status actually exceeded the minimum return condition threshold for a majority of the disputed systems. That finding narrowed the legitimate return condition claims considerably and contributed to a settlement for roughly a third of the lessor's original demand.

Fuel Burn Testing Data Undercuts an Engine Performance Guarantee Claim

An airline sued an engine manufacturer alleging that a new engine variant failed to meet the fuel burn performance guarantees specified in the purchase agreement, seeking significant compensation for excess fuel costs incurred across its fleet since delivery. The engine manufacturer retained an aerospace expert with engine performance testing and flight data analysis experience to compare the airline's reported in-service fuel burn data against the manufacturer's certified test-cell performance data and the specific operating conditions the guarantee applied under. The expert found that a substantial share of the reported fuel burn shortfall was attributable to the airline's own route network and payload patterns falling outside the guarantee's reference conditions, rather than any engine performance deficiency. That analysis significantly narrowed the airline's viable claim and led to a settlement covering only the portion of the shortfall attributable to conditions within the guarantee's scope.

Certificate Traceability Review Exposes a Counterfeit Parts Supply Chain

An aircraft component manufacturer sued a parts distributor after discovering that a shipment of fasteners supplied for use in a safety-critical assembly lacked valid material traceability, forcing the manufacturer to recall and re-inspect thousands of installed assemblies at significant cost. The manufacturer retained an aerospace expert with parts quality and traceability experience to trace the fastener lot's documented chain of custody back through the distributor's records and compare the certificates of conformance against the mill's actual production records. The expert found the certificates accompanying the disputed lot did not correspond to any batch the certifying mill had actually produced, and that the distributor's own receiving inspection records showed the discrepancy had been flagged and then overridden. That finding established the distributor's failure to maintain adequate traceability controls and was pivotal in the manufacturer's recovery of recall costs.

Telemetry Reconstruction Resolves a Satellite Launch Failure Liability Dispute

A satellite operator sued its launch services provider after a launch vehicle anomaly resulted in the satellite being placed into an unusable orbit and declared a total loss, with the launch provider disputing that the failure fell within the vehicle-caused anomaly categories covered by the launch services agreement's liability provisions. The satellite operator retained an aerospace expert with launch vehicle systems and telemetry analysis experience to reconstruct the vehicle's second-stage burn performance from recovered telemetry data and compare it against flight parameters from prior successful missions. The expert found a valve in the stage's propellant feed system had underperformed relative to its qualification testing baseline beginning several seconds before stage separation, consistent with a vehicle hardware anomaly rather than the ground-based guidance error the launch provider had proposed. That reconstruction supported the operator's claim that the failure fell within the agreement's vehicle-fault liability provisions and was central to the operator's recovery under the agreement.

Source Code Comparison Uncovers Stolen Flight Control Software

A defense avionics company sued a former lead software engineer and the competing company he joined, alleging he had taken proprietary flight control software architecture and used it to accelerate a competing autopilot system to market roughly two years ahead of its expected development timeline, in a dispute over a valuable program. The plaintiff retained an aerospace expert with flight control systems and software architecture experience to compare the accused system's control loop structure, fault detection logic, and code organization against the plaintiff's proprietary source code. The expert found several idiosyncratic function naming conventions and an unusual fault-handling sequence with no functional necessity appeared nearly identically in both codebases. That comparison became central evidence of trade secret misappropriation and contributed to a settlement that included a licensing payment and development restrictions on the competing autopilot.

Flight Test Data Integrity Review Resolves a Certification Lab Negligence Claim

An aircraft manufacturer sued the independent test lab it had engaged to perform structural fatigue testing in support of a new aircraft's type certification after regulators identified inconsistencies in the test data that delayed certification by more than a year, costing the manufacturer significantly in delayed deliveries and additional testing. The manufacturer retained an aerospace expert with structural testing and certification experience to review the lab's test setup records, load cell calibration history, and raw data logs against the certification test plan both parties had agreed to follow. The expert found a load cell used for a substantial share of the test cycles had exceeded its calibration interval by several months without documented re-verification, a lapse inconsistent with the lab's own quality procedures. That finding established the lab's departure from proper testing controls and was central to the manufacturer's recovery of a significant portion of its delay-related costs.
