OPERATION OF CRANES AND TALL STRUCTURES IN THE VICINITY OF
NEWCASTLE AIRPORT
Reference:
A. AC 139-08(0) – CASA Advisory Circular – Reporting of Tall Structures
INTRODUCTION
1.
Restrictions are placed on the airspace surrounding an airfield in order to protect the
aircraft flying in and out of that airfield. To ensure safety is not compromised and to limit
restrictions to aircraft operations, a process of requesting permission to erect cranes or tall
structures in the vicinity of the airfield is required.
AIM
2.
The aim of this document is to detail the procedures to gain approval to erect a crane
or other tall structure within the vicinity of Newcastle Airport in order to protect aviation
activities, both civilian and military, at this aerodrome.
SCOPE
3.
This instruction details the procedures to seek approval to erect a crane or tall
structure within 15 km of Newcastle Airport, shown in annex A.
4.
Any persons looking to erect a crane or tall structure beyond 15 km should consult
reference A and if necessary raise the matter with the Directorate of External Land
Planning
(DELP)
within
Defence
Support
Group
via
email
at
[email protected].
DEFINITIONS
5.
The following definitions are applicable in the context of this instruction:
a.
Permanent Obstruction. An object which will breach an obstacle clearance
surface and is fixed or irremovable or, if mobile, is deliberately situated for
operational purposes and not intended to be decommissioned as long as the
facility that it is a part of remains in use.
b.
Transient/Temporary Obstruction. An object, such as a road vehicle or
crane, which will breach the obstacle-free area or surface for only a short
period of time.
PERMANENT OBSTRUCTION
6.
Permanent structures have a potential to pose an indefinite imposition on aviation
safety or operations and must be assessed by DELP. Assessments by DELP must occur on
structures when they meet one of the following conditions:
a.
proposed structures located within the Newcastle Airport precinct, as shown in
figure one of annex A;
2
b.
proposed structures exceeding 15 m Australian Height Datum (AHD) within a
3 km radius of Newcastle Airport, as shown in figure two of annex A–2;
c.
proposed structures exceeding 30 m AHD within a 15 km radius from
Newcastle Airport, as shown in figure three of annex A–3;
d.
proposed structures with a height of 30 m or more above ground level (GL)
within 30 km of Newcastle Airport; and
e.
proposed structures with a height of 45 m or more above GL beyond 30 km of
Newcastle Airport.
TEMPORARY OBSTRUCTION
7.
Temporary obstructions, dependent on the height and location, will be processed
locally through the Air Base Command Post (ABCP) for compilation on a local task
register. ABCP will provide a response advising if approval is granted and any operating
restrictions, if appropriate.
Request for Approval of Temporary Obstructions
8.
A request for approval must be submitted to the ABCP email box,
[email protected], in the following situations:
a.
use of any cranes or tall structures on the airside at Newcastle Airport;
b.
any cranes or tall structures exceeding 10 m above GL 1 within Newcastle
Airport precinct, as shown in figure one of annex A;
c.
any cranes or tall structures exceeding 15 m Australian Height Datum (AHD)
within a 3 km radius of Newcastle Airport, as shown in figure two of annex A–
2; and
d.
all cranes and any tall structures exceeding 30 m above GL within a 15 km
radius from Newcastle Airport, as shown in figure three of annex A–3.
9.
All applicants are to provide a completed copy of the form, at enclosure 1, to the
ABCP at least two business days prior to the intended use of the crane or erection of the
tall structure. The ABCP will:
a. provide the applicant with a notice of approval which will detail any
requirements or special instructions for the structure, or
b. decline the request with reason.
1
Ground level (GL), rather than Australian Height Datum (AHD), is used as the criteria for temporary obstruction assessment due to the
temporary nature of these activities. Generally surveyors are not engaged in these activities and as such information relating to their level
above AHD is not easily accessible or understood. The increased risk of using GL is mitigated by the relatively flat land surrounding the
base and the more stringent limits set by this instruction over the actual Obstacle Limitation Surface (OLS) heights.
3
10.
Requests for use of a crane or erection of a tall structure provided to ABCP with
less than two business days will not be supported unless for emergency reasons.
11.
The application process is shown in annex B.
12. Applicants requesting approval of cranes must ensure they provide contact details
with their request documentation that enable the ABCP to notify the operator/supervisor
directly to lower the crane at short notice.
13. The applicant is to ensure the works are undertaken in accordance with the
instructions and any provisions or restrictions provided by the ABCP. Any proposed
changes outside the scope of the original approval are to be forwarded to ABCP for
consideration against the original approval.
ABCP Responsibilities
14. The ABCP is to manage requests for use of cranes or tall structures (temporary)
within 15 km of Newcastle Airport.
15. The ABCP is to arrange publishing of a Notice to Airmen (NOTAM) where
necessary in accordance with reference A.
