Compliance safety vs front-line safety: Understanding the disconnect in aircraft maintenance

Abstract

The aircraft maintenance industry is governed by highly regulated safety systems that emphasize procedural compliance, documentation and audit conformity. While these systems ensure traceability and standardization, an overreliance on rule-following can inadvertently obscure the complex, adaptive realities of frontline maintenance work. This study introduces and contrasts two paradigms—compliance safety, which equates safety with procedural adherence and front-line safety, which recognises safety as the outcome of context-sensitive decision-making, resilience and informal adaptation. The compliance safety framework (CSF) is proposed as a conceptual model illustrating how excessive proceduralising and audit logic may mask real-world risks and suppress vital frontline feedback. Through a synthesis of human factors literature, cross-industry case comparisons and the author's direct operational experience, the study critiques the assumption that regulatory compliance alone ensures safety. It aligns the CSF with, and contrasts it to, Safety-I, Safety-II and Just Culture, revealing how institutional misapplication of these models may weaken their efficacy. Furthermore, the paper advocates for an integrative approach where adaptive leadership, competence beyond certificates and diplomas and dynamic safety management systems (SMS) play pivotal roles in bridging the procedural-practical divide. The findings argue for a cultural and systemic shift, from enforcing compliance to enabling adaptability, while preserving regulatory integrity. The article concludes by outlining practical recommendations and proposes future empirical testing of the CSF model to assess its applicability across diverse aviation contexts.
