Warning On Plagiarism And Collusion

Plagiarism and collusion are forms of cheating and are not acceptable in any form of a student’s work, including this assignment. You can avoid plagiarism by giving appropriate references when you use some other people’s ideas, words or pictures (including diagrams). Refer to the American Psychological Association (APA) Manual if you need reminding about quoting and referencing. You can avoid collusion by ensuring that your submission is based on your own individual effort.

The electronic submission of your assignment will be screened through a plagiarism detecting software, Turnitin.

For more information about plagiarism and cheating, you should refer to the Student Handbook. SUSS takes a tough stance against plagiarism and collusion. Serious cases will normally result in the student being referred to SUSS’s Student Disciplinary Group. For other cases, significant marking penalties or expulsion from the course will be imposed.

Responsible Use Of Generative Ai Tools

While tools like Generative AI, such as ChatGPT, can generate responses, they lack the ability to comprehend the specific content of your assignment. This may lead to irrelevant or erroneous answers that could negatively affect your grades. If you choose to utilize such tools, it is crucial to verify and adopt the generated content in your own words.

Question 1

Table Q1a shows the failure data of three aircraft components collected from an aircraft fleet over a 3-year period. Using relevant technical formulae and working details, discuss how you could use the MS Excel application to construct the Weibull Probability Plot for each component. Evaluate the shape parameter and scale parameter from each best-fit line(s).

(20 marks)

Question 2

A total of 5 counts of failures were recorded for an electro-mechanical aircraft component used on a new fleet of 10 aircraft. The time-to-failure for these failure events are tabulated in Table Q1b.

Table Q1b – Failure Data Recorded for An Aircraft Component

Using the Median Rank method, discuss the steps taken to process the failure data and present the processed data points on the Weibull Plot Paper provided in Annex A. Evaluate the shape parameter and the scale parameter from the Weibull Plot, outlining clearly how each of these parameters can be obtained from the plotted graph and derive the prevailing failure pattern seen on the aircraft component.

Question 3

Appraise Prognostics Maintenance and discuss its applications on commercial transportation aircraft. Illustrate your write-up with specific, relevant aircraft examples.

Question 4

The Malacca Straits Patrol is undertaken by Indonesia, Malaysia, Singapore and Thailand to ensure the security of the Straits of Malacca and Singapore. It is a set of cooperative measures comprising the Malacca Straits Sea Patrol, the “Eyes-in-the-Sky” Combined Maritime Air Patrols as well as the Intelligence Exchange Group.

The Electronic Flight Instrument System (EFIS) installed on the Fokker-50 (F-50) Maritime Patrol Aircraft has been experiencing an increasing failure rate over the last 6 months. An experienced avionics engineer suggested imposing a regime of the weekly removal of the affected EFIS for thorough functional checks carried out in the backend workshop. The procedure in the Aircraft Maintenance Manual (AMM) requires the EFIS to be removed from the F-50 aircraft for corrective maintenance only when it fails to function in flight.

Evaluate if this additional proactive maintenance strategy of removing the EFIS (for complete functional checks to be carried out at the backend workshop at regular weekly intervals) will be effective to improve its operational reliability and thus enhance the overall aircraft availability.

Question 5

The Republic of Kawkiki Air Force (RKAF) operates a total of 280 F-16C/D Fighting Falcon aircraft. Its exceptional agility and maneuverability makes it a formidable force in air-to-air combat with its precise handling and responsive controls giving pilots an edge in dogfights. However, there were three engine related crashes in the last nine months in Kawkiki; these crashes have raised an alert on its F-16 powered by a single Prat & Wally F101-PW-2299. As such, the engine OEM Prat & Wally has raised a special safety service bulletin for a review on the F101-PW-2299 engine Spectrometric Oil Analysis Programme (SOAP).

What is the Spectrometric Oil Analysis Programme (SOAP)? Assess whether SOAP is a Hard Time or an On-Condition or a Condition Monitoring maintenance type. Use appropriate justifications for your answers.

(12 marks)

Question 6

Discuss how the SOAP process can be designed to prevent total engine component failure during flight operations and thus improve the safety of the F-16.

(5 marks)

Question 7

The Fokker 50 (F-50) of Republic of Allbeania Air Force (RAAF) is a turboprop-powered aircraft used to transport army troopers. The failure data of Symbol Generator of the F-50 is documented throughout its lifespan and illustrated in the Weibull plot displayed in Figure Q2(b). The purpose of the Symbol Generator is to display the attitude and relative position of the aircraft and it is an essential component in the cockpit before the declaration of the serviceability of the F-50.

Figure Q6 – Weibull Plot of F-50 Symbol Generator

(a) The Weibull plot revealed two distinct lines, Line 1 and Line 2. Recommend how this finding may offer insights into the reliability performance of the Symbol Generator throughout its life cycle.

(4 marks)

(b) Evaluate and determine the shape factor for Line 1 and Line 2, detailing the methodology or approach you would use to determine the shape factor for Line 1 and Line 2 respectively. Recommend an approach for analysing the shape factors to understand the conditional probability of failure pattern for the F-50 Symbol Generator.

(6 marks)

(c) Evaluate and assess the reliability of the F-50 Symbol Generator after it has been in operation for 700,000 hours of flight time. Recommend and propose a replacement interval for the F-50 Symbol Generator to maintain a minimum reliability of 85% in operation.

(4 marks)

Question 8

Aster-30 air defence radar has the capability to intercept targets at altitudes from 50 m to 20 km against aircraft targets flying at altitudes above 3 km, the maximum range of the Aster-30 is 100 km. If the detection computer of the Aster-30 is designed with a MTBF of 1.1 million hours, and it is operated 24 hours per day, evaluate and analyse the failure rate per year.

(5 marks)

Question 9

Construct the On-Condition maintenance scope for Lockheed C-130 Hercules Main Landing Gear Shock Strut and assess how the maintenance interval can be established. Explain why the P-F interval is a crucial component of the P-F curve and how it impacts the maintenance process.

(5 marks)

Question 10

Gulfstream Aerospace Corporation (GAC) is an American aircraft company and a subsidiary of General Dynamics. Gulfstream designs, develops, manufactures, markets, and services business jet aircraft. The RAMS (Reliability, Availability, Maintainability and Safety) disciplines are a set of tools that GAC utilises to ensure that their aircraft fulfills the mission for which it was designed, all under the conditions of reliability, maintainability, availability and more importantly the well-defined safety records.

Assess and evaluate the goals and guidelines for each RAMS target to determine how they will be measured in the context of aircraft maintenance.
