Abstract

This dissertation explores the impact of barriers on MROs' spare part delivery needs,

addressing a gap in existing literature. A comprehensive literature review confirmed the study's

relevance, noting the scarcity of studies on military aircraft maintenance, repair, and overhaul

in the UAE. Three hypotheses were formulated to understand operations and supply chain

teams' perspectives. An independent sample t-test analyzed role differences between operations

and supply chain employees, regression analysis assessed challenges' impact on productivity,

and structural equation modeling evaluated effects on on-time delivery. Non-probability

sampling yielded 214 respondents from GAL, UAE, who completed a seven-point Likert scale

questionnaire. The instrument's reliability and validity were confirmed through pilot testing.

Confirmatory factor analysis examined OEM collaboration, technological obstacles, inventory

accuracy, inventory quality, supply chain transparency, spare parts tracking, manpower factors,

and demand forecasting. Results showed high model fitness for challenges and OEM

collaboration with CMIN/DF:1.428, χ2: 2560.603, RMSEA and SRMR < 0.08, and GFI, AGFI,

NFI, IFI, TLI, and CFI exceeding 0.9. Operations teams had lower parameters, except

manpower, compared to supply chain teams (M=3.853, SD=0.702) and t= -1.875, df=201, p=

0.040; P>.05. The study suggests new MRO efficiency measures, impacting operations and

supply chain, and recommends addressing resistance hindering productivity. Future research

could explore different MROs, nations, or employee groups, considering other significant

variables.
