"Safety, punctuality, and service" is the core management that Shanhang has always pursued. In recent years, Shanhang's core capabilities such as civil aviation safety, punctuality and service have ranked among the top in the industry. During the 12th Five-Year Plan period, the company's fleet average growth rate was 13.4%, more than 3 percentage points higher than the industry average, and passenger transport volume has steadily increased.
, as one of the "safety" control barriers, has been in full swing in recent years from the management model to improve it; starting from the aspects of engineering maintenance and results, and creating a first-class maintenance and management model in China.
Process control strengthens safety awareness. The daily utilization rate of aircraft is the highest in China. According to the management policy of "safety first, prevention first", Shanhang Engineering Technology Company has implemented a series of management measures such as consolidating a safety foundation, strengthening the full-process control of maintenance, building and implementing a reliability management mechanism, and strictly controlling maintenance costs. It has strict process control in terms of safety and quality management, fault and defect handling, maintenance plan formulation and implementation, and maintenance cost control. In terms of
security management, Shanhang has established an SMS security management system, adhered to the principle of "safety first and prevention first", established a mechanism of "risk identification and risk control", and used the method of "data analysis and system evaluation" to improve the foundation of "safety culture and safety training". In terms of fault and defect handling in
, Shanhang, on the premise of ensuring safety, efficiently completes fault and defect handling and resumes flight operations. According to the relevant person in charge of Shanhang Equestrian, Shanhang Engineering Technology Company will sort out maintenance resources in advance, timely formulate a disposal plan, reasonably organize on-site implementation and actively provide technical support, and improve the disposal ability of the foreign commissioned maintenance units. Through the exchange of air-ground data, important system operation information is monitored, faults are discovered in advance and prepared to be prepared to sort out the faults in previous years, sort out the TOP12 projects and control them to improve system reliability.
uses the AMMS (mechanical and financial integration) system as the platform to realize the full process closed-loop control of maintenance work. Based on the fleet maintenance plan and combined with capacity requirements, long-term, medium- and short-term rolling maintenance plans should be prepared according to the rolling maintenance plan, production preparation should be implemented, maintenance resources should be reasonably allocated to ensure production based on maintenance guarantee resources, repair tasks should be decomposed, and closed-loop management of production instructions should be implemented according to the results of production instructions, production analysis should be carried out, and maintenance plans should be revised according to the evaluation information.
In terms of cost control, Shanhang has established a complete maintenance cost control system and carefully grasped the management, forming a maintenance cost control model with Shanhang's characteristics and leading domestic maintenance cost control model. Taking the "Engineering and Technology Company Maintenance Cost Control Plan" as the main line, deepen supplier business cooperation and promote Air China flight cooperation; formulate a three-level organizational structure and working mechanism for the maintenance cost control leading group, cost control working group, and department/maintenance base cost control working group; establish a system support for "management support, indicator control, project entry, and awareness cultivation".
In addition, Shanhang has established long-term and stable cooperative relationships with aircraft manufacturing companies including Boeing and Bombardier, aviation material suppliers such as GE, Honeywell and Collins, as well as external maintenance units such as Shandong Swire, AMECO, and Air France-KLM, to achieve mutual benefit and win-win results. There are 173 aviation materials suppliers, a total of 76 analysis, laboratory and verification units, a total of 16.
At the same time, Shanhang also has a complete management system in terms of emergency management. Shanhang Engineering Technology Company has specially established an emergency management organization for the emergency management, compiled an emergency management manual, formulated and implemented emergency drill plans every year, summarized drill experience, and revised and improved the manual. "We will regularly organize typhoon prevention drills, ice and snow removal drills, hangar fire drills, etc.," said a relevant person in charge of Shanhang.
. In terms of daily aircraft utilization, Shanhang has achieved outstanding results in recent years, and in 2016, the daily aircraft utilization rate ranked first in China. Among them, the flight management has put a lot of effort into the maintenance of the aircraft parking lot. "We optimize the maintenance plan and implement precise control of maintenance tasks." said the person in charge of Shanhang flight management.
It is understood that Shanhang Engineering Technology Company sorted out the maintenance capacity control process, established a planned control platform, maximized project intervals and optimized maintenance plans, shortened the parking cycle and strengthened production scheduling, deepened the linkage and cooperation of multi-department maintenance preparation, and reasonably reduced planned parking.Through the effectiveness control of the process implementation, Shanhang saves an average of 3 days of parking per aircraft per year. Based on the scale of 100 aircraft in the fleet, it is equivalent to increasing the capacity of one aircraft every year, and indirectly increasing revenue by 7.64 million yuan.
Aircraft must be inspected for 6,000 hours per flight. The process of withdrawing and renting the plane is not simple
It is understood that the maintenance of the aircraft is carried out by route maintenance combined with regular maintenance. All maintenance projects shall be carried out in accordance with the maintenance plan. Route maintenance is guaranteed by pre-flight, station pass and post-flight.
regular maintenance adopts centralized maintenance in the aircraft parking lot. According to the inspection time interval, it is mainly divided into low-level fixed inspection, high-level fixed inspection and time-limit maintenance projects. According to the model maintenance plan, the flight cycle, flight hours and calendar days are controlled separately. Taking the Shanhang Boeing 737-800 aircraft as an example, the aircraft needs to complete a low-level regular inspection (P inspection) every 450 flight hours; and the high-level regular inspection (C inspection) needs to complete a high-level regular inspection (C inspection) every 6,000 flight hours.
aircraft disposal and withdrawal of lease is the final stage of aircraft full life project management. Since 2010, Shanhang has completed the disposal and withdrawal of 18 aircraft of three types.
aircraft disposal and lease refund work are divided into three main stages according to time: delivery preparation, delivery inspection execution stage and aircraft delivery stage. Among them, the delivery preparation phase spans from one year before delivery to one week before delivery inspection. The main work includes notifying the aircraft for withdrawal time and adjusting the aircraft technical status. Prepare the first draft of technical documents, prepare the delivery of inspection work content and confirm the work package. The aircraft mechanism is restored to the reception state, and the initial documents are prepared.
delivery inspection execution stage from the entry of the aircraft to the release of the aircraft. During this period, engineers must perform the delivery inspection work, perform the verification test flight required by the lease contract, test flight rear row failure, prepare all maintenance records for the delivery inspection, and sign and release the delivery inspection according to CAAC and FAA standards.
The aircraft delivery stage is within 10 working days after the delivery inspection and release. Engineers need to inspect the aircraft engine holes, update the technical documents and cancel the lease technical documents, and finally revise/sign the lessor finally reviews the aircraft and technical documents, negotiates the legacy project, and signs the aircraft handover.
On May 26, 2017, Shanhang cooperated with the leasing company to complete the processing of the export airworthiness certificate and cancellation documents for the B-5321 aircraft. At this point, the B-5321 aircraft officially withdrew from the Shanhang fleet, which is also the first Boeing 737NG aircraft that Shanhang has withdrawn from lease. Taking this aircraft as an example, six months before the lease refund, the Shanhang Association established a special lease refund team, led by Shanhang Engineering Technology Company, involving Shandong Swire Aircraft Engineering Co., Ltd., Shanhang Investment and Procurement Department, Finance Department, Flight Department, Cabin Department and other departments, with nearly 100 related personnel.
When the aircraft is withdrawn from lease, all maintenance files of the aircraft will be cleaned, classified, scanned and inspected; some parts on the aircraft need to be replaced, collected, repaired and tested; the entire surface of the aircraft must be repainted to meet the requirements of the leaser, and all discovered damages will be evaluated, recorded and repaired; all flight information during the aircraft rental period will be reviewed in detail one by one.
The withdrawal team must complete the relevant withdrawal work within the specified time in accordance with the requirements of the lease contract and then hand over the aircraft to the leaseholder. It can be said that completing the lease cancellation means completing the management of the aircraft in the field of maintenance, which allows you to have a clearer understanding of the entire process of aircraft maintenance and control.
