Factual and Procedural Background
The Plaintiff, employed as a flight attendant by Company A, alleges personal injuries sustained due to a "hard" or "abrupt" landing of an aircraft during a transatlantic flight on 28 June 2019 at Boston Airport. The Plaintiff initiated a personal injuries action against Company A. The current judgment concerns an application for the discovery of documents relevant to the case, specifically focusing on whether records of flight data monitoring and cockpit voice recordings should be disclosed.
Legal Issues Presented
- Whether discovery of flight data monitoring records and cockpit voice recordings is appropriate in the context of the personal injuries claim.
- How Regulation (EU) No 996/2010 on the investigation and prevention of accidents and incidents in civil aviation applies to the disclosure of such records.
- The balancing of interests between the administration of justice and the confidentiality and safety concerns inherent in aviation safety records.
- The scope and limits of discovery concerning confidential and sensitive documents under Irish law and EU Regulation.
Arguments of the Parties
Plaintiff's Arguments
- The Plaintiff seeks discovery of cockpit voice recordings and flight data monitoring records related to the flight during which injuries were alleged.
- The Plaintiff argues that such documents are necessary to establish negligence in the landing of the aircraft.
- Discovery of documents relating to repairs to the seat, floor beams, or safety harness used by the Plaintiff is also sought to support claims of inadequate maintenance.
- Requests discovery of documentation regarding the make, model, year of manufacture of the aircraft, seat position, and safety harness configuration.
- Seeks discovery of records concerning other cabin crew members allegedly injured on the same flight to support the severity of the landing.
Defendant's Arguments
- Company A resists discovery of cockpit voice recordings primarily on the basis of Regulation (EU) No 996/2010, which restricts disclosure of such sensitive aviation safety records.
- Argues that flight data monitoring records for a limited period (five seconds before and after touchdown) are sufficient to assess landing forces and that cockpit voice recordings would not add meaningful information.
- Offers to discover entries in the flight log referring to the landing and limited flight data monitoring records within a ten-second window around touchdown.
- Agrees to limited discovery of repair records but initially proposes a 24-hour timeframe, citing operational complications.
- Contests relevance of documents related to other cabin crew injuries as speculative.

Court's Reasoning and Analysis
The court began by emphasizing that the relevance of documents for discovery is determined by the pleadings and the issues to be tried, following established Irish case law. It applied a balancing test for confidential documents, weighing their materiality against the confidentiality interests, particularly in the context of aviation safety.
The court noted that Regulation (EU) No 996/2010 restricts disclosure of certain aviation safety records, including cockpit voice recordings and flight data monitoring records, except where the administration of justice requires disclosure that outweighs adverse impacts on safety investigations.
Applying these principles, the court refused discovery of cockpit voice recordings because the Plaintiff had not shown necessity beyond the availability of flight data monitoring records, which cover landing forces relevant to the claim. Disclosure of cockpit voice recordings was deemed unlikely to provide meaningful additional information and posed risks to aviation safety and pilot privacy.
The court accepted the Defendant’s offer to provide flight data monitoring records limited to five seconds before and after touchdown, finding this timeframe reasonable and proportionate to the Plaintiff’s needs. The court allowed for the possibility of further discovery if this data indicated a harder-than-normal landing requiring additional information.
Regarding repair records, the court found the Plaintiff’s request relevant and extended the period for discovery from 24 hours to one week before and after the flight to allow a realistic timeframe for repairs to be recorded.
The court also ordered discovery of documents relating to the make, model, seat position, and safety harness configuration of the aircraft, as well as documentation identifying seating locations of other cabin crew members allegedly injured, finding these relevant to the Plaintiff’s claim.
The court’s approach reflected an incremental and balanced method to discovery, respecting confidentiality while ensuring fairness in litigation.
Holding and Implications
The court ORDERED discovery in respect of the following categories, subject to modifications:
- Flight data monitoring records limited to five seconds before and after touchdown.
- Records of flight log entries relating to the landing.
- Documents concerning repairs to the seat, floor beams, and safety harness within one week before and after the flight.
- Documentation regarding the aircraft’s make, model, year, seat position, and safety harness configuration.
- Documents identifying seating locations of other cabin crew members allegedly injured on the same flight.
Discovery of cockpit voice recordings was REFUSED due to lack of demonstrated necessity and the overriding public interest in protecting aviation safety and confidentiality.
The Plaintiff was granted liberty to apply for further discovery if initial disclosed materials indicate a need. The court provisionally ordered that each party bear its own costs of the discovery motion, reflecting partial success on both sides.
No new legal precedent was established; the decision primarily applied and clarified existing principles balancing discovery rights with confidentiality and regulatory protections in aviation-related litigation.
