    A framework for assessment of quality management system of aircraft maintenance organizations in Tanzania
    (University of Dar es Salaam, 2020) Sanga, Furaha
    A framework for assessment of quality management system of aircraft maintenance organizations in Tanzania Furaha Sanga Master of Engineering Management (MEM) University of Dar es Salaam, COET, 2020 Quality of maintenance is one among the top three causes of aviation accidents. From 2014 to 2018, in Tanzania accident related to aircraft maintenance has increase by 48.99% per annum. This study assessed and establishes a framework for QMS implementation by Approved Maintenance Organizations (AMOs) in Tanzania. This study used surveys, focus group discussion (FGD) and interviews. Key informants were; managers, auditors, academicians, accident investigators and inspectors. Data were analysed using SPSS and SmartPLS. It assessed 8 QMS principles, 20 QMS elements, 13 barriers and 16 key performance indicators (KPIs). For QMS principles, ‘Process approach’ mean of 3.9 and ‘involvement of people' mean of 3.61 were the highest and lowest respectively. For QMS elements, ‘Inspection and testing’ mean of 4.22 and ‘management responsibility’ mean of 3.78 were the highest and lowest respectively. These values were below the mean of 4.51-5.00 which implies ‘fully implemented’. This implies that QMS is not fully implemented. ‘Lack of top management commitment’ mean of 2.73 and Tack of fund’ mean of 3.21 were the highest and lowest barrier respectively to affect QMS. Since mean of 1.00-3.50 indicates barrier affect QMS, all barriers were found affecting QMS. ‘Fleet average time left to maintenance’ and ‘time taken to accomplish maintenance’ were the only KPIs found within recommended targets. The established framework can be employed by AMO management for effective QMS implementation. This study enriched knowledge in the areas of QMS implementation which is still low in Tanzania. This study is applicable only to AMOs hence future study must cover other aviation entities.
