SAFETY NEWSLETTER

HAPPY NEW YEAR 2018 I hope everybody had a good break during the New Year’s holiday. On this 6th

issue of AC Aviation Safety Newsletter, we will look at some of the aircraft parts that are considered dangerous goods if they are shipped or being delivered on

board our aircrafts. We do at times getting aircraft parts delivered back and forth from HPA in Singapore that could be hazardous during flight, so I would like all of

us to take extra cautious on this part.

Last year we went through a lot of Root Cause Analysis in dealing with AOCR. Root cause Analysis can be difficult if you do not know where to start in solving the situation, this is where the ‘5 Whys’ method comes in handy. There are also many different methods, but on this article, we will be focusing on the ‘5 Whys’ method.

Improving Safety Culture is always an important factor in AC Aviation, that is why I came up with the Safety Culture Manifesto.

I hope you enjoy reading this issue of Safety Newsletter and have a SAFE year ahead!

AIRCRAFT PARTS THAT

ARE DANGEROUS GOODS.. THAT

YOU MAY NOT BE AWARE O F

1. A I R C R A F T T I R E S If the tire assembly you are shipping is

damaged, it will be forbidden to fly unless

certain special provisions are followed. It is

also important to mention that some airlines interpret the rules differently and

have their own policies, which can and do vary from station to station.

If in doubt, when placing an order inform the Sterling Representative that the commodity shipped is an aircraft tire. We

will help you

determine if the assembly is subject to the regulations or if additional steps must be taken in order to move the shipment via air.

When shipping a tire assembly for your

AOG aircraft, tires that are ready for use

are not considered as Dangerous Goods

unless they are damaged or inflated

beyond the maximum pressure

recommended by the manufacturer.

2 . AVIONICS C O N T A I N I N G LITHIUM BATTERIES

Knowing in advance the shipment details can help us make appropriate arrangements, therefore ensuring regulatory compliance and most efficient routing.

Certain aircraft parts, such as avionics components, contain lithium batteries. Depending on the

type and weight of the batteries, your shipments may require special handling or may be transported by air on cargo aircraft only.

3. E X I T S I G N S

When you are shipping any type of instrument, sign or device that has the ability to glow in the

dark, such as an exit sign, you may be moving small amounts of radioactive materials.

To ensure your shipment is not delayed, you must determine the radioactive element and

activity level and then properly classify the item. Depending on the level of radiation, your

shipment may be allowed as Radioactive Materials, Excepted Package. If this is the case the

Radioactive Material, Excepted Package label is required, but not the Shipper's Declaration.

4. L I F E R A F T S

Although life rafts may not seem hazardous,

after all they are meant to save lives, some are

regulated by the IATA DGR. If your raft has a

description “Life-saving appliances, self-

inflating”, you have to ship it as a Dangerous

Good (UN 2990).

In addition to presenting a hazard if the self-

inflating device is accidentally activated, many

life-saving appliances also contain additional

dangerous goods which may pose a hazard.

When packaged and declared according to

regulation, these devices and their contents

may be safely and legally transported.

"Making prior arrangements" is especially

important since some airlines do not accept magnetized items in any form. We have come

across situations when shippers did not inform us that their shipments contained magnetized material. The package was then

rejected by the airline due to their acceptance policy, a situation that would be easily

avoided had we known all the details ahead of time.

It is always advisable to inform the Sterling Representative about the type of the aircraft part you ship. They will help you determine if the

part is subject to the regulations or if additional

steps must be taken in order to move the shipment via air.

5. M A G N E T I Z E D M A T E R I A L S

Any type of magnetized material being shipped on an aircraft can potentially be

deemed as Dangerous Good as it can interfere with the instruments on the aircraft.

Even though not all magnetized materials will

require a Dangerous Goods Declaration, you must inform Sterling that the material

shipped is magnetized as it may require special handling procedures, which includes

making prior arrangements with the operator identifying the magnetized material.

ROOT CAUSE ANALYSIS (RCA) GUIDANCE

A RCA is a structured evaluation method that identifies;

1. The root causes for an undesired outcome;

2. The actions adequate to prevent recurrence.

The RCA process should continue until all

organizational factors have been identified, or until all data are exhausted. There are many different methods of

carrying out the RCA process. One of the most useful methods frequently used within the airline industry is the;

"5 WHY's" problem solving technique.

The "5 Whys" is a method using a questions-

asking process to explore the cause/effect

relationships underlying a particular problem.

5 Why's Example

Q: WHY has machine stopped? Q: WHY overload trip? Q: WHY Insufficient oil?

A: Overload tripped out! A: Insufficient oil on shaft! A: Oil pump inefficient!

Root - Cause

Q: WHY is pump not efficient? Q: WHY is this shaft worn?

A: Pump drive shaft worn! A: Oil filter blocked with swarf!
