Purpose: This study develops and validates a strategic human resource development model tailored to the requirements of Iran’s aviation industries. Methodology: An applied-developmental, exploratory-validation mixed-method design was used. Initial strategies were derived from a targeted literature review and an analysis of human, technological, and safety challenges, and were refined with 60 managers, senior experts, and specialists. Fifteen experts then assessed model comprehensiveness, structural logic, and implementability using a nine-item questionnaire and open-ended responses. The formative model was tested using partial least squares structural equation modeling. Findings: Mean scores for comprehensiveness, structure and relationships, implementability, and overall evaluation were 4.65, 4.40, 4.20, and 4.42 out of 5, respectively. Convergent validity was 0.78, variance inflation factors ranged from 1.85 to 2.95, and all formative weights were significant at the 95% confidence level. R2 was 0.68 and SRMR was 0.072. Digital skill development and technology localization had the largest relative weights; however, approximate pairwise Wald tests did not confirm statistically distinct weights. Conclusion: The final model organizes ten strategies into foundational drivers, organizational enablers, and strategic outcomes. It offers an actionable framework for competency development, talent retention, burnout reduction, and technological capability building under the resource and safety constraints of specialized aviation organizations.
