The Market leader, Boeing 777 is entirely a twin-engine jetliner, efficient in fuel utilization acknowledged by airlines and passengers all over the globe, Boeing proceeds to growing this family as a result of current introductions of the 777-200LR Worldlier as well as the development of the novel 777 Freighter. Based on the present statistics, the Boeing has sold approximately 827 777s as well as the delivery of 556 to 46 lease operators and airlines globally. With more concern on the stewardship of the cash generation of the Boeing 777 aircraft(Yeh, 2015). There is need to develop an effective maintenance program that will evidently translate to an advanced and elongated lifecycle of the aircraft in addition to ensuring a significant cost-benefit analyses aspect. Besides, as a result of the increased market competition, it is essential for every given company to ensure that there are proper maintenance practices and modification of the past maintenance program with an objective of outcompeting their immediate competitors as well as ensuring that there is substantial cost-benefit analysis. The paper will address the present aircraft life cycle maintenance plans of the Boeing 777.

In order to reduce maintenance costs of the Boeing 777, increase revenue generations as well as improving its life cycle. The following are the improvements to be adjusted to the already scheduled maintenance programs of the aircraft. It is important to acknowledge that the reduction of specific maintenance tasks would significantly reduce maintenance by at least over 400 hours of labor, per every airplane within every year. Alternatively, it will be giving the airlines additional days of service each year for every 777 within their fleet. As in accordance to Yeh (2015), this will reduce the maintenance costs as well as increase opportunities or revenue generation revenue of over $100,000 on yearly revenue of every Boeing 777 in operation.

There should be an extension of the interval of inspecting the maintenance program typically for the zonal operations. For instance, areas such as the fuselage compartments, doors, struts as well as the flight controls should be inspected after every 37 months rather than the initial 37 months respectively. In regard to the initial Maintenance Review Board (MRB) report, the plane could be away from service for approximately five days undergoing checks on the maintenance required after a period of every 25 months. The increment of additional 12 months towards such maintenance interval of will provide considerable scheduling and financial opportunities to the 777 operators. Furthermore, this interval will capacitate customers with the industry-leading maintenance program relative to the retention of similar safety and the reliabilities inherited in the 777 bowing model. Evidently, the extension interval will enhance the reduced cost of maintenance and life cycle due to limited disturbance of the delicate plane parts as well as increased revenues for all the airlines aircraft (Badkook, 2016).

Additionally, other new maintenance program that should be escalated include general inspections which were initially undertaken after every 100 days but presently, it is advised to be performed after every 125 days as in accordance with the eight-month efforts of the Industry Steering Committee (ISC) constituting of the Boeing 777 airliner operators, regularity, and Boeing authorities. This modified maintenance program is attributed to sharing of data by typical operators in conjunction with the fast response by the Boeing Company after extensive research had been carried out(Badkook, 2016). Moreover, an effective accomplishment of these intervals will prompt a substantial percentage of the structures and the systems as well as the zonal tasks which will help each and every individual to eliminate incidences of non-value addition of performing some tasks too often or too early.

In summary, maintenance plan or program of an aircraft it the most vital activity that must be taken into account to ensure that there is elongated lifecycle, improved functionality of the plane, increased revenue generation, efficiency in conjunction with a competitive advantage towards other airlines.
